CHAPTER

Cisco Analog Telephone Adaptor Overview

This section describes the hardware and software features of the Cisco Analog Telephone Adaptor (Cisco ATA) and includes a brief overview of the H.323 protocol.

The Cisco ATA analog telephone adaptors are handset-to-Ethernet adaptors that allow regular analog telephones to operate on IP-based telephony networks. Cisco ATAs support two voice ports, each with an independent telephone number. The Cisco ATA 188 also has an RJ-45 10/100

This section covers the following topics:

• H.323 Overview, page 1-2

H.323 Overview

H.323 is the International Telecommunication Union (ITU) standard for transmitting voice, video, and data across an IP network. Like other VoIP protocols, the H.323 standard is designed to address the functions of signaling and session management from within a packet telephony network. Signaling allows call information to be carried across network boundaries. Session management provides the ability to control the attributes of an end-to-end call. The H.323 standard includes support for call signaling and control, multimedia transport and control, and bandwidth control for both point-to-point and point-to-multipoint conferences.

The H.323 standard includes the following protocols:

• Call signaling using the H.225 protocol

• Media control using the H.245 protocol

• G.711, G.722, G.723, G.728, and G.729 audio codecs

• H.261 and H.263 video codecs

• Data sharing using the T.120 protocol

• Real-time transport protocol (RTP) and RTP Control Protocol (RTCP) for media transport

Chapter 1 Cisco Analog Telephone Adaptor Overview

Components that the H.323 standard employs include a system of interconnected voice terminals, gateways, gatekeepers, multipoint control units (MCUs), and proxy servers. Voice terminals provide point-to-point and point-to-multipoint conference capability for audio, video, and data. Voice gateways interconnect the packetized IP network to the PSTN or ISDN network. Gatekeepers provide admission control and address translation services for H.323 voice terminals and gateways. MCUs enable two or more gateways to engage in point-to-point or point-to-multipoint audio or video conferences.

This section contains descriptions of the following H.323 components:

• H.323 Terminals, page 1-3

• H.323 Gateways, page 1-3

• H.323 Gatekeepers, page 1-4

H.323 Terminals

Voice terminals in an H.323 network must feature system control units, media transmission capabilities, audio codecs, and network interfaces suitable for transmitting and receiving packetized data.

H.323 Gateways

H.323 gateways feature a mixture of characteristics of both standard Switched Circuit Network (SCN) access points and H.323 access points. Gateways perform the translation of audio, video, and data transmission formats as well as interacting with communications systems and various protocols. A primary responsibility of an H.323 gateway is the call setup and teardown necessary to complete a call to and from a packetized IP network and a standard switched network.

H.323 Overview

H.323 Gatekeepers

Gatekeepers are primarily responsible for pre-call and call-level control services for H.323 gateways. Gatekeepers are an optional component in an H.323 system. However, if present, gatekeepers must perform the following call setup and management services:

• Address translation for IP addresses originating from H.323 aliases (for example,

address_pool@cisco.com, for example) or E.164 addresses (for example, standard telephone numbers)

• Admissions control for authorizing or rejecting access to H.323

• Bandwidth control for gateway bandwidth requirements

• Zone management for registered voice terminals, gateways and MCUs

When used in an H.323 system, gatekeepers can also (but are not required to) provide the following functionality:

• Call control signaling using the gatekeeper Routed Call Signaling model

• Call authorization to restrict access to certain voice terminals or gateways, or to restrict access based

on time-of-day criteria

Chapter 1 Cisco Analog Telephone Adaptor Overview

• Bandwidth management for the H.323 system that will enable the gateway to restrict access when

requested bandwidth is unavailable

• Call management including maintaining a list of active calls to indicate available and unavailable

voice terminals and gateways

H.323 MCUs

MCUs are endpoints in an H.323 network that support point-to-multipoint conferences and consist of a multipoint controller and at least one multipoint processor responsible for receiving voice, video, and data streams. These streams are distributed to access points participating in a point-to-multipoint conference.

H.323 Proxy Server

An H.323 proxy server is a proxy specifically designed for the H.323 protocol and examines packets between two communicating applications. Proxies can determine the destination of a call and perform call-connection steps, if necessary.

H.323 proxies perform the following key functions:

• Allow voice terminals that do not support Resource Reservation Protocol (RSVP) to connect to the

proxy through remote access or local area networks with relatively reliable quality of service (QoS). Pairs of proxies can then be employed to develop tunnels across the IP network.

• Support routing of H.323 traffic that is separate from ordinary data traffic by using

application-specific routing (ASR).

• Enable H.323 to be deployed in networks that use private address space.

• Ensure network security by configuring the proxy server to allow only H.323 traffic over the

network.

CHAPTER

Configuring the Cisco ATA for H.323

This section describes how to configure the Cisco ATA to operate with the H.323 signaling image and how the Cisco ATA obtains the latest signaling image.

You can configure the Cisco ATA for use with H.323 with any of the following methods:

• By using a TFTP server—This is the Cisco-recommended method for deploying a large number of

Cisco ATAs. This method allows you to set up a unique Cisco ATA configuration file or a configuration file that is common to all Cisco ATAs. The Cisco ATA can automatically download its latest configuration file from the TFTP server when the Cisco ATA powers up, is refreshed or reset, or when the specified TFTP query interval expires.

• By using manual configuration:

–

Voice configuration menu—This is the method you must use if the process of establishing IP connectivity for the Cisco ATA requires changing the default network configuration settings. These settings are CDP, VLAN, and DHCP. You also can use the voice configuration menu to review all IP connectivity settings. The voice configuration menu can also be used when Web access is not available.

–

Web-based configuration—This method is convenient if you plan to deploy a small number of Cisco ATAs in your network. To use this method, the Cisco ATA must first obtain IP connectivity, either through the use of a DHCP server or by using the voice configuration menu to statically configure IP addresses.

This section contains the following topics:

• Default Boot Load Behavior, page 3-2—This section describes the process that the Cisco ATA

follows by default when it boots up. It is very important to understand this process because, if your network environment is not set up to follow this default behavior, you need to make the applicable configuration changes. For example, by default, the Cisco ATA attempts to contact a DHCP server for the necessary IP addresses to achieve network connectivity. However, if your network does not use a DHCP server, you must manually configure various IP settings as described in this section.

• Specifying a Preconfigured VLAN ID or Disabling VLAN IP Encapsulation, page 3-3—This section

includes a table of the parameters you can configure for VLAN and CDP settings.

• Steps Needed to Configure the Cisco ATA, page 3-5—This section provides tables that summarize

the general configuration steps you must follow to configure the Cisco ATA.

• Configuring the Cisco ATA Using a TFTP Server, page 3-8—This section describes procedures for

configuring the Cisco ATA by using a TFTP server, which is the recommended configuration method for the deployment of a large number of Cisco ATAs.

• Voice Configuration Menu, page 3-20—This section includes information on how to obtain basic

network connectivity for the Cisco ATA and how to perform a factory reset if necessary.

Default Boot Load Behavior

Note The term Cisco ATA is used throughout this manual to refer to both the Cisco ATA 186 and the

Cisco ATA 188, unless differences between the Cisco ATA 186 and Cisco ATA 188 are explicitly stated.

Chapter 3 Configuring the Cisco ATA for H.323

• Cisco ATA Web Configuration Page, page 3-23—This section shows the Cisco ATA Web

configuration page and contains a procedure for how to configure Cisco ATA parameters using this interface.

• Refreshing or Resetting the Cisco ATA, page 3-25—This section gives the procedure (via the Web

configuration page) for refreshing or resetting the Cisco ATA so that your most recent configuration changes take effect immediately.

• Obtaining Cisco ATA Configuration File After Failed Attempt, page 3-26—This section gives the

formula for how soon the Cisco ATA attempts to fetch its configuration file from the TFTP server after a failed attempt.

• Upgrading the H.323 Signaling Image, page 3-26—This section provides references to the various

means of upgrading your Cisco ATA signaling image.

Default Boot Load Behavior

Before configuring the Cisco ATA, you need to know how the default Cisco ATA boot load process works. Once you understand this process, you will be able to configure the Cisco ATA by following the instructions provided in this section and in the sections that follow.

All Cisco ATAs are shipped with a bootload signaling-protocol image. However, because this image is not a fully functional signaling image, the image must be upgraded. The image is designed to be automatically upgraded by a properly configured TFTP server. To configure the Cisco ATA to automatically upgrade to the latest signaling image, see the “Upgrading the Signaling Image from a

TFTP Server” section on page 8-1.

In addition, the Cisco ATA obtains its configuration file during the bootload process.

The following list summarizes the default Cisco ATA behavior during its boot-up process:

1. The Cisco ATA uses the Cisco Discovery Protocol (CDP) to discover which VLAN to enter. If the

Cisco ATA receives a VLAN ID response from the network switch, the Cisco ATA enters that VLAN and adds 802.1Q VLAN tags to its IP packets. If the Cisco ATA does not receive a response with a VLAN ID from the network switch, then the Cisco ATA assumes it is not operating in a VLAN environment and does not perform VLAN tagging on its packets.

Note If your network environment is not set up to handle this default behavior, make the necessary

configuration changes by referring to the “Specifying a Preconfigured VLAN ID or Disabling

VLAN IP Encapsulation” section on page 3-3.

2. The Cisco ATA contacts the DHCP server to request its own IP address.

Note If your network environment does not contain a DHCP server, you need to statically configure

various IP addresses so that the Cisco ATA can obtain network connectivity. For a list of parameters that you must configure to obtain network connectivity, see Table 3-6 on page 3-21. For instructions on how to use the voice configuration menu, which you must use to perform this configuration, see the “Voice Configuration Menu” section on page 3-20.

3-2

OL-4804-01

Page 39

Chapter 3 Configuring the Cisco ATA for H.323

3. Also from the DHCP server, the Cisco ATA requests the IP address of the TFTP server.

4. The Cisco ATA contacts the TFTP server and downloads the Cisco ATA release software that

contains the correct signaling image for the Cisco ATA to function properly.

Note If you are not using a TFTP server, you need to manually upgrade the Cisco ATA to the correct

signaling image. For information on this procedure, see the “Upgrading the Signaling Image

Manually” section on page 8-2.

5. The Cisco ATA looks for a Cisco ATA-specific configuration file (designated by the MAC address

of the Cisco ATA and named ata<macaddress> with a possible file extension) on the TFTP server and downloads this file if it exists. For information about configuration file names, see the

“Configuration Files that the cfgfmt Tool Creates” section on page 3-13.

6. If the Cisco ATA does not find an ata<macaddress> configuration file, it looks for an atadefault.cfg

configuration file and downloads this file if it exists. This file can contain default values for the Cisco ATA to use.

Note When the Cisco ATA is downloading its DHCP configuration, the function button on the top panel

blinks.

Specifying a Preconfigured VLAN ID or Disabling VLAN IP Encapsulation

If you want the Cisco ATA to use a preconfigured VLAN ID instead of using the Cisco Discovery Protocol to locate a VLAN, or if you want to disable VLAN IP encapsulation, refer to Tabl e 3 - 1 for a reference to the parameters and bits you may need to configure. Use the voice configuration menu to configure these parameters. (See the “Voice Configuration Menu” section on page 3-20 for instructions on using this menu.) Also, refer to Tab l e 3-2 for a matrix that indicates which VLAN-related parameters and bits to configure depending on your network environment.

Note Bits are numbered from right to left, starting with bit 0.

Example

The following procedure shows you how to configure the OpFlags and VLANSetting parameters to allow the Cisco ATA to use a user-specified VLAN ID. In this example, the voice VLAN ID is 115 (in decimal format).

Step 1 Set bits 4-6 of the OpFlags parameter to 1, 0, and 1, respectively. This setting translates to the following

bitmap:

xxxx xxxx xxxx xxxx xxxx xxxx x101 xxxx

The remaining bits of the OpFlags parameter, using all default values, make up the following bitmap representation:

0000 0000 0000 0000 0000 0000 0xxx 0010

Therefore, the resulting value of the OpFlags parameter becomes the following bitmap representation:

0000 0000 0000 0000 0000 0000 0101 0010

Chapter 3 Configuring the Cisco ATA for H.323

In hexadecimal format, this value is 0x00000052.

Step 2 Set bits 18-29 of the VLANSetting parameter to to voice VLAN ID 115. This setting translates to the

following bitmap

xx00 0001 1100 11xx xxxx xxxx xxxx xxxx

where 000001110011 is the binary representation of the demical value 115.

The remaining bits of the VLANSetting parameter, using all default values, make up the following representation:

00xx xxxx xxxx xx00 0000 0000 0010 1011

Therefore, the resulting value of the VLANSetting parameter becomes the following bitmap representation:

0000 0001 1100 1100 0000 0000 0010 1011

In hexadecimal format, this value is 0x01cc002b.

Note If you are using the voice configuration menu to set the parameters, you must convert hexadecimal

values to decimal values. For example, the OpFlags setting of 0x00000052 is equivalent to 82 in decimal format, and the VLANSetting of 0x01cc002b is equivalent to 30146603 in decimal format.

d. Place the unique binary configuration file on the TFTP

server.

3. Optionally, create a default configuration file called

atadefault.cfg, which the Cisco ATA will download from the TFTP server only if the unique Cisco ATA file called ata<macaddress> (with a possible file extension) does not exist on the TFTP server. For information about possible configuration file names, see the “Configuration Files that the cfgfmt Tool

Creates” section on page 3-13.

4. Configure the upgradecode parameter so that the Cisco ATA will

obtain the correct signaling image from the TFTP server when the Cisco ATA powers up.

5. Configure the desired interval for the Cisco ATA to contact the

TFTP server to check for a configuration-file update or an upgrade of the signaling image file.

6. Configure the method with which the Cisco ATA will locate the

TFTP server at boot up time.

7. Power up the Cisco ATA.

8. If you make configuration changes to the Cisco ATA or upgrade

the signaling image on the TFTP server, you can refresh the Cisco ATA so that these changes take effect immediately. Otherwise, these changes will take effect when the specified interval (CfgInterval parameter value) for the TFTP query expires.

This section provides the procedure for the Cisco ATA administrator to obtain the correct Cisco ATA software and set up the TFTP server with this software.

Procedure

Step 1 If you are a registered CCO user. go to the following URL:

http://www.cisco.com/cgi-bin/tablebuild.pl/ata186

Step 2 Download the zip file that contains the software for the applicable release and signaling image you are

using. The contents of each file are described next to the file name. Save the zip file onto a floppy disc.

Note The file that contains the protocol signaling image has an extension of .zup.

Step 3 Extract the signaling files onto the TFTP server. This should be the same TFTP server that will contain

the binary Cisco ATA configuration file that you create (either ata<macaddress> with a possible file extension or atadefault.cfg). For information about possible configuration file names, see the

“Configuration Files that the cfgfmt Tool Creates” section on page 3-13.

Configurable Features and Related Parameters

Table 4-1 on page 4-2 contains a list of all required H.323 parameters. These parameters must be

properly configured for the Cisco ATA to work.

For descriptions of important Cisco ATA H.323 services that you can configure, and references to their configuration parameters, see the “Important Basic H.323 Services” section on page 4-1 and the

“Additional H.323 Services” section on page 4-7.

Table 4-4 on page 4-12 lists, in alphabetical order, various features that you can configure for the

Cisco ATA. Table 4-4 on page 4-12 also includes links to the related parameter that allows you to configure each of these features. Each link takes you to a detailed description of the parameter that includes its default values.

Chapter 3 Configuring the Cisco ATA for H.323

Configuring the Cisco ATA Using a TFTP Server

For an example of how to configure parameters for the TFTP Server configuration method, see the

“Creating Unique and Common Cisco ATA Configuration Files” section on page 3-9.

Creating Unique and Common Cisco ATA Configuration Files

If you have many Cisco ATAs to configure, a good approach is to create two configuration files:

• One file that will contain only parameter values unique to a specific Cisco ATA.

• One file for parameters that will be configured with values common to a group of Cisco ATAs. If

this file is updated, all Cisco ATA devices in this common group can obtain the new configuration data in a batch-mode environment.

The following procedure demonstrates the steps needed to create these configuration files.

Note The parameters used in this section help illustrate the process of creating a unique Cisco ATA

configuration file, and do not include all required H.323 parameters in the examples. See Chapter 4,

“Basic and Additional H.323 Services,” for complete listings and descriptions of required parameters

and additional configurable features. Also, refer back to Table 3-3 on page 3-6 for all main configuration steps.

Procedure

Step 1 Use the h323_example.txt file as a template for creating a text file of values that are common to one

group of Cisco ATAs. The h323_example.txt file is included in the software-release zip file and contains all default values. This file is shown without its annotations in the “Configuration Text File Template”

section on page 5-2.

Copy the h323_example.txt file and save it with a meaningful name, such as common.txt.

Step 2 Configure all common parameters by editing the text file as desired. For example, you might configure

the following parameters:

UseTftp:1 DHCP:1 TFtpURL:10.10.10.1

The settings in this example indicate that a group of Cisco ATAs is using the TFTP server with an IP address of 10.10.10.1 to obtain their configuration files. These Cisco ATAs will use a DHCP server to obtain their own IP addresses but not to obtain the TFTP server IP address (because the TftpURL parameter has a configured value).

Step 3 Save your changes.

OL-4804-01

3-9

Page 46

Configuring the Cisco ATA Using a TFTP Server

Step 4 Use the h323_example.txt file again, this time as a template for creating a text file of values that are

specific to one Cisco ATA. For example, you might configure the following parameters:

UserID:8530709 GkorProxy:192.168.1.1

Save this file of Cisco ATA-specific parameters as:

ata<macaddress>.txt

where macaddress is the non-dotted hexadecimal version of the MAC address of the Cisco ATA you are configuring. This non-dotted hexadecimal MAC address is labeled on the bottom of most Cisco ATAs next to the word “MAC.” The file name must be exactly 15 characters long. (However, if this filename is supplied by the DHCP server, the name can be as long as 31 characters and can be any name with printable ASCII characters.)

If necessary, you can obtain the non-dotted hexadecimal MAC address by using the atapname.exe command. For information on using the atapname.exe command, see the “Using atapname.exe Tool to

Obtain MAC Address” section on page 3-11. That section includes an example of a dotted decimal MAC

address and its corresponding non-dotted hexadecimal address.

Note The ata<macaddress>.txt file should contain only those parameters whose values are different

from the file of common parameters. Parameter values in the ata<macaddress> configuration file will overwrite any manually configured values (values configured through the web or voice configuration menu) when the Cisco ATA powers up or refreshes.

Chapter 3 Configuring the Cisco ATA for H.323

Step 5 On the top line of the ata<macaddress>.txt file, add an include command to include the name of the

common-parameters file, and save the file.

include:common.txt UserID:8530709 GkorProxy:192.168.1.1

Step 6 Run the cfgfmt.exe tool, which is bundled with the Cisco ATA software, on the ata<macaddress>.txt

text file to generate the binary configuration file. If you wish to encrypt the binary file, see the “Using

Encryption With the cfgfmt Tool” section on page 3-12.

The syntax of the cfgfmt program follows:

Syntax

cfgfmt [Encryption options] -h323 -tptag.dat input-text-file output-binary-file

–

Encryption options are described in the “Using Encryption With the cfgfmt Tool” section on

page 3-12.

–

Chapter 3 Configuring the Cisco ATA for H.323

Example

cfgfmt -h323 -tptag.dat ata0a141e28323c.txt ata0a141e28323c

This example is based on a Cisco ATA MAC address of 10.20.30.40.50.60, which converts to the two-digit, lower-case hexadecimal representation of each integer as 0a141e28323c.

When you convert the ata<macaddress>.txt file to a binary file, the binary file will merge the two text files to form one Cisco ATA-specific binary configuration file for your Cisco ATA.

If the same parameter is configured with different values in these two files, the value in the ata<macaddress>.txt file takes precedence over the value in the common.txt file.

Step 7 Store all binary configuration file(s) in the TFTP server root directory. For information about possible

configuration file names, see the “Configuration Files that the cfgfmt Tool Creates” section on

page 3-13.

When the Cisco ATA powers up, it will retrieve its configuration file(s) from the TFTP server.

Step 8 If you want to make configuration changes after boot up, repeat the process of creating or editing the

text files containing the desired parameters, then converting the ata<macaddress>.txt text file to the binary file(s) and storing the binary file(s) on the TFTP server. For the configuration changes to take effect immediately, refresh the Cisco ATA. (See the “Refreshing or Resetting the Cisco ATA” section on

page 3-25.)

Configuring the Cisco ATA Using a TFTP Server

After being refreshed, the Cisco ATA will download the updated ata<macaddress> configuration file(s).

Note If you do not perform a refresh procedure, the Cisco ATA will update its configuration the next

time it contacts the TFTP server, which is based on the configured value of the CfgInterval parameter.

Using atapname.exe Tool to Obtain MAC Address

This bundled tool is useful for converting the dotted decimal version of the Cisco ATA MAC address (available on the Cisco ATA Web configuration page or from the voice configuration menu code 24#) to its default Cisco ATA profile name. This name has the following format:

ataxxxxxxxxxxxx

where each xx is the two-digit, lower-case hexadecimal representation of each integer in the dotted, decimal version of the Cisco ATA MAC address. This is the name you use for the unique Cisco ATA binary configuration file.

Command Output

Note The same functionality is available from the voice configuration menu (voice menu code 84#), which

will announce the Cisco ATA profile name.

Using Encryption With the cfgfmt Tool

The EncryptKey or EncryptKeyEx parameter can be used to encrypt binary files that are transferred over TFTP. You can change encryption keys for each Cisco ATA so that only one specific Cisco ATA can decode the information.

Chapter 3 Configuring the Cisco ATA for H.323

Cisco strongly recommends using the EncryptKeyEx parameter for encryption because this parameter provides a stronger encryption than the EncryptKey parameter that was used in Cisco ATA software releases prior to release 2.16.

You must use version 2.3 of the cfgfmt configuration-file generation tool to use the new EncryptKeyEx parameter. This tools comes bundled with Cisco ATA software version 3.0. To verify that you have version 2.3 of the cfgfmt tool type the following command:

cfgfmt

The version number of the cfgfmt tool will be returned.

You can configure the EncryptKeyEx parameter by using the Cisco ATA Web configuration page or by using the TFTP configuration method. (For more information, see the “EncryptKeyEx” section on

page 5-7.)

You can configure the EncryptKey parameter by using the Cisco ATA Web configuration page, the voice configuration menu, or by using the TFTP configuration method. (For more information, see the

“EncryptKey” section on page 5-6.)

By default, the Cisco ATA-specific ata<macaddress> configuration file(s) are not encrypted. If encryption is required, however, you must manually configure the EncryptKeyEx or EncryptKey parameter before you boot up the Cisco ATA so that the TFTP method is secure. The Cisco ATA uses the RC4 cipher algorithm for encryption.

Note Because the factory-fresh ATA cannot accept encrypted configuration files, the first unencrypted file, if

intercepted, can easily be read. (You would still have to know the data structure format in order to decode the binary information from the unencrypted file.) Therefore, the new encryption key in the unencrypted file can be compromised.

Note For security reasons, Cisco recommends that you set the UIPassword parameter (if desired) in the

configuration file and not by using one of the manual configuration methods.

Configuration Files that the cfgfmt Tool Creates

The number of output binary configuration files that the Cisco ATA produces is dependent on two factors:

• Which encryption key parameter is used—EncryptKey or EncryptKeyEx

• The total size of the binary output

Table 3-5 shows the names of the binary files that can be generated. One, two or four files can be

generated.

Note <macaddress> in Tab le 3 -5 is the MAC address of the Cisco ATA.

Configuring the Cisco ATA Using a TFTP Server

Note If you are creating an atadefault configuration file, the generated binary file name will be

atadefault.cfg.x if you encrypt the text file with the EncryptKeyEx parameter; the binary file name will be atadefault.cfg if you do not use the EncryptKeyEx parameter to encrypt the text file. For information on creating an atadefault configuration file, see the “atadefault.cfg Configuration File” section on

page 3-17.

cfgfmt Tool Syntax and Examples

The syntax of the cfgfmt tool follows:

Syntax

cfgfmt [options] input output

Syntax Definitions—Options

• -eRc4Passwd—This option directs the Cisco ATA to use Rc4Passwd as the key (up to eight

hexadecimal characters) to encrypt or decrypt the input text file. However, if the Cisco ATA EncryptKey parameter in the input text file is not 0, then the value of that parameter is used to encrypt the output binary file, and Rc4Passwd is ignored. The -e portion of this option means that the Cisco ATA will use the weaker encryption method.

• -E—This option directs the Cisco ATA to not use the value of the EncryptKey parameter, as set in

the input text file, to encrypt the output binary configuration file.

• -xRc4Passwd—This option directs the Cisco ATA to use Rc4Passwd, which must be a hexadecimal

string of as many as 64 characters, as the key to encrypt or decrypt the input text file. However, if the Cisco ATA EncryptKeyEx parameter in the input text file is not 0, then the value of that parameter is used to encrypt the output binary file, and Rc4Passwd is ignored. The -x portion of this option means that the Cisco ATA will use the stronger encryption method.

Chapter 3 Configuring the Cisco ATA for H.323

• -X—This option directs the Cisco ATA to not use the value of the EncryptKeyEx parameter, as set

in the input text file, to encrypt the output binary configuration file.

• -tPtag.dat—This file, provided with the Cisco ATA software version you are running, is used by the

cfgfmt tool to format a text input representation of the parameter/value pairs to its output binary representation. Be sure this file resides in the same directory from which you are running the cfgfmt program.

• -sip—Specify this tag if you are using the SIP protocol so that the cfgfmt tool will include only the

SIP protocol parameters in the converted output binary file.

• -h323—Specify this tag if you are using the H.323 protocol so that the cfgfmt tool will include only

the H.323 protocol parameters in the converted output binary file.

• -mgcp—Specify this tag if you are using the MGCP protocol so that the cfgfmt tool will include

only the MGCP protocol parameters in the converted output binary file.

• -sccp—Specify this tag if you are using the SCCP protocol so that the cfgfmt tool will include only

the SCCP protocol parameters in the converted output binary file.

• -g—This tag omits sensitive parameters in an ata<macaddress> file that was created with a version

of the cfgfmt tool prior to version 2.3.

Some parameters, specified in the ptag.dat file used by the cfgfmt tool, are marked as sensitive information (these parameters could include UIPassword, UID, PWD0). These parameters are not included in the output binary file if the -g switch is specified in the cfgfmt syntax.

Syntax Definitions—Required Parameters

• Input—This is the input text file representation of the Cisco ATA configuration file.

• Output—This is the final output binary file that Cisco ATA uses as the TFTP configuration file.

OL-4804-01

Page 51

Chapter 3 Configuring the Cisco ATA for H.323

Syntax examples

The cfgfmt.exe syntax affects how the EncryptKeyEx or EncryptKey parameters are used, as shown in the following examples. In these examples, input-text-file is the ata<macaddress>.txt file that you will convert to binary to create the ata<macaddress> configuration file(s) for the Cisco ATA; output-binary-file is that binary ata<macaddress> file, and Secret is the encryption key.

• cfgfmt -h323 -tptag.dat input-text-file output-binary-file

If input-text-file sets the Cisco ATA EncryptKey parameter to 0, then output-binary-file is not encrypted. If the input-text-file sets EncryptKey to a non-zero value, then output-binary-file is encrypted with that value.

• cfgfmt -X -h323 -tptag.dat input-text-file output-binary-file

This is an example of how you might perform encryption on a first-time Cisco ATA.

The -X (uppercase) option means that any value specified for the Cisco ATA EncryptKeyEx parameter in input-text-file is ignored. However, because Secret is not specified in this example, output-binary-file is not encrypted. Nevertheless, the EncryptKeyEx parameter and its value, if specified in input-file-text, will be included in output-binary-file for possible encryption at a later time. The next time the Cisco ATA fetches the configuration file from the TFTP server, the file will be encrypted with Secret.

• cfgfmt -X -xSecret -h323 -tptag.dat input-text-file

output-binary-file

Configuring the Cisco ATA Using a TFTP Server

This is an example of changing the encryption key from one key to another key.

The -X (uppercase) option means that any value specified for the Cisco ATA EncryptKeyEx parameter in input-text-file is ignored and the output-binary-file is encrypted with the Secret key. However, the EncryptKeyEx parameter and its value, if specified in input-text-file, will be included in output-binary-file.

Examples of Upgrading to Stronger Encryption Key

This section contains two examples of how you would upgrade your Cisco ATA configuration to use the stronger encyrption method if the current Cisco ATA firmware version was a version earlier than version

2.16.2. Versions earlier than 2.16.2 do not support the stronger EncryptKeyEx parameter.

Example 1

In this example, the Cisco ATA has not yet been deployed, but its firmware version is earlier than 2.16.2. Therefore, the Cisco ATA will upgrade to to firmware version 3.0 to use the EncryptKeyEx parameter as its encryption key.

The Cisco ATA in this example has a MAC address of 102030405060.

Perform the following steps:

Procedure

Step 1 Create a file called ata102030405060.txt by using the applicable example.txt file provided with the

Cisco ATA software. (For example, for H.323, the example.txt file is called h323_example.txt.)

Step 2 Modify the ata102030405060.txt file with desired parameter values. The value of the EncryptKey

parameter should be 0.

Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide for H.323 (version 3.0)

OL-4804-01

3-15

Page 52

Configuring the Cisco ATA Using a TFTP Server

Step 3 Set the value of the EncryptKeyEx parameter to the chosen encryption key with which you want the

output binary file to be encrypted. In the EncryptKeyEx parameter specified in the configuration file, you can also restrict the EncryptKeyEx value to apply only to the Cisco ATA with a particular MAC address. For example, if the chosen key value is 231e2a7f10bd7fe, you can specify EncryptKeyEx as:

EncryptKeyEx:231e2a7f10bd7fe/102030405060

This means that only the Cisco ATA with the MAC address 102030405060 will be allowed to apply this EncryptKeyEx value to its internal configuration.

Step 4 Update the upgradecode parameter to instruct the Cisco ATA to upgrade to firmware version 3.0 by

means of TFTP configuration. The upgradecode parameter is described in Chapter 8, “Upgrading the

Cisco ATA Signaling Image.”

Step 5 Run the cfgfmt tool as follows:

cfgfmt -g ata102030405060.txt ata102030405060

This will generate the following two binary configuration files:

• ata102030405060

• ata102030405060.x

ata102030405060 is unencrypted.

ata102030405060.x is encrypted with EncryptKeyEx value.

Chapter 3 Configuring the Cisco ATA for H.323

Step 6 Place these two files on the TFTP server that the Cisco ATA will contact for its configuration files.

When the Cisco ATA powers up, it will obtain its IP address from the DHCP server. If the DHCP server specifies the TFTP server address, the Cisco ATA will contact the TFTP server obtained from DHCP because the Cisco ATA is not preconfigured with a TFTP server address. The boot process is as follows:

a. The Cisco ATA downloads the configuration file ata102030405060 from the TFTP server. b. The Cisco ATA applies parameter values in the file ata102030405060 to its internal

configuration while ignoring the EncryptKeyEx parameter (because the older version of the Cisco ATA does not yet recognize the EncryptKeyEx parameter).

c. The Cisco ATA upgrades to the 3.0 firmware load. d. The Cisco ATA reboots. e. The Cisco ATA again downloads the configuration file ata102030405060.

f. The Cisco ATA applies the value of the EncryptKeyEx parameter to its internal configuration. g. The Cisco ATA reboots. h. The Cisco ATA EncryptKeyEx value is in effect, so from this point forward the Cisco ATA will

download the ata102030405060.x file at each reboot and each time the value configured in the CfgInterval parameter expires.

Note Although EncryptKeyEx is encrypted in the ata<macaddress> file, and the ata<macaddress> file

does not contain other sensitive information, Cisco recommends that for absolute security you pre-configure the Cisco ATA as described in this example for a private network. Alternatively, you should remove ata<macaddress> once EncryptKeyEx takes effect.

3-16

OL-4804-01

Page 53

Chapter 3 Configuring the Cisco ATA for H.323

Example 2

In this example, a new Cisco ATA has already b een deployed (with the EncryptKey value set) with a firmware version earlier than 2.16.2. The Cisco ATA needs to be upgraded to version 2.16.2 firmware or greater to use EncryptKeyEx parameter to encrypt its configuration file.

In this scenario, you would follow the same procedure as in Example 1, except that you would need to set the EncryptKey value to the previously configured EncryptKey value. The difference is that the ata<macaddress> file is now encrypted with EncryptKey because the Cisco ATA expects the ata<macaddress> file to be encrypted with EncryptKey.The Cisco ATA can then begin using the ata<macaddress>.x file that is encrypted with the EncryptKeyEx parameter.

atadefault.cfg Configuration File

You can create a configuration file, called atadefault.cfg, that is common to all Cisco ATAs. This configuration file is applied to a Cisco ATA only if a unique configuration file (such as ata<macaddress>) does not exist for the Cisco ATA on the TFTP server during the Cisco ATA power-up procedure.

You can use the atadefault.cfg file to provide limited functionality for when you first install the Cisco ATA. For example, if your service provider provides the ethernet connection and VoIP telephony service, you may need to call customer service to activate the service. If the atadefault.cfg file is configured to provide a direct connection to the customer service center, you can simply pick up the telephone and wait to be connected without using your regular phone.

Configuring the Cisco ATA Using a TFTP Server

The following procedure illustrates how to create the Cisco ATA default configuration file, convert it to the required binary format that the Cisco ATA can read, and store it on the TFTP server so that the Cisco ATA will download it during the boot-up process:

Procedure

Step 1 Make a copy of the h323_example.txt file and rename it atadefault.txt. Step 2 Make the desired configuration changes by editing the atadefault.txt file, then save the file. Step 3 Convert the atadefault.txt file to a binary file by running the cfgfmt.exe tool, which is bundled with the

Cisco ATA software.

Note If you wish to encrypt the binary file for security reasons, see the “Using Encryption With the

cfgfmt Tool” section on page 3-12. If you encrypt the file using the EncryptKeyEx parameter,

the resulting binary file will be called atadefault.cfg.x; if not encrypted with the EncryptKeyEx parameter the resulting binary file name will be atadefault.cfg.

Step 4 Store the binary atadefault.cfg (or atadefault.cfg.x) configuration file in the TFTP server root directory.

During the boot-up process, the Cisco ATA will download this file as its configuration file unless it first finds a Cisco ATA-specific configuration file named for the MAC address of the Cisco ATA.

Chapter 3 Configuring the Cisco ATA for H.323

Configuring the Cisco ATA Using a TFTP Server

Configuring the Cisco ATA to Obtain its Configuration File from the TFTP Server

This section describes three methods for how the Cisco ATA contacts the TFTP server to obtain its configuration file:

• Using a DHCP Server, page 3-18

–

The Cisco ATA contacts the DHCP server, which provides the IP address of the TFTP server

–

The Cisco ATA uses the DHCP server but the DHCP server does not know about the TFTP server

• Without Using a DHCP Server, page 3-20

Using a DHCP Server

When using a DHCP server, configuration settings vary depending on whether or not the DHCP server is under the control of the Cisco ATA system administrator or the service provider. The simplest configuration is when the DHCP server is under the control of the Cisco ATA administrator, in which case the DHCP server provides the IP address of the TFTP server. Depending on who controls the DHCP server, follow the applicable configuration procedure:

• Procedure if DHCP Server is Under Control of Cisco ATA Administrator, page 3-18

• Procedure if DHCP Server is not Under Control of Cisco ATA Administrator, page 3-19

This section also includes the topic:

• Other DHCP Options You Can Set, page 3-19

Note If no DHCP server is found and the Cisco ATA is programmed to find one, the function button

continues to blink.

Procedure if DHCP Server is Under Control of Cisco ATA Administrator

Procedure

Step 1 On the DHCP server, set one of the following two options:

• DHCP option 150 (TFTP server IP address)

• Standard DHCP option 66 (TFTP server name)

If you use DHCP option 150, the Cisco ATA will ignore DHCP option 66. However, if you use DHCP option 66, you must turn off DHCP option 150 or set its value to 0.

Note You can turn off the DHCP option 150 request by using the Cisco ATA OpFlags parameter (see

the “OpFlags” section on page 5-34).

Step 2 Make sure to use default values for the following Cisco ATA parameters:

• TftpURL=0

• UseTftp=1

• DHCP=1

Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide for H.323 (version 3.0)

3-18

OL-4804-01

Page 55

Chapter 3 Configuring the Cisco ATA for H.323

This completes the parameter settings and DHCP options you need to configure for this procedure. The Cisco ATA will contact the DHCP server for the IP address of the TFTP server that contains the Cisco ATA configuration file.

Procedure if DHCP Server is not Under Control of Cisco ATA Administrator

This is the procedure to use if the DHCP server is not under the control of the Cisco ATA administrator, which means that the URL of the TFTP server must be manually configured.

Procedure

Step 1 Using the voice configuration menu, set the parameter TftpURL to the IP address or URL of the TFTP

server. For more information on setting the TftpURL parameter, see the “TftpURL” section on page 5-5. For information about using the Cisco ATA voice configuration menu, see the “Voice Configuration

Menu” section on page 3-20.

Note If you are not using a DHCP server to provide the TFTP server location, you must manually

configure the TftfURL. You can do this by using the voice configuration menu without first obtaining network connectivity for the Cisco ATA. If you want to configure this value using the Web configuration page, you first must obtain network connectivity by using the voice configuration menu to statically configure IP address information (see the “Voice Configuration

Menu” section on page 3-20).

Configuring the Cisco ATA Using a TFTP Server

Step 2 Use the default value of 1 for the Cisco ATA parameter DHCP. Step 3 Use the default value of 1 for the Cisco ATA parameter UseTftp.

This completes the parameter settings you need to configure for this procedure. The Cisco ATA will contact the manually configured TFTP server that contains the Cisco ATA configuration file.

Other DHCP Options You Can Set

The following parameters can also be configured with DHCP:

• Boot file name of DHCP header—The ata<macaddress> binary Cisco ATA configuration file,

which can have a maximum of 31 characters and can be any name with printable ASCII characters

• Client PC address

• DHCP option 1—Client Subnet Mask

• DHCP option 3—Routers on the client’s subnet

• DHCP option 6—One or two Domain Name servers

• DHCP option 42—One or two Network Time Protocol servers

Note DHCP options 43 and 60 are set by the Cisco ATA. Option 43 specifies the protocol and option 60

identifies the vendor class of the Cisco ATA box.

Page 56

Voice Configuration Menu

Without Using a DHCP Server

Use the following procedure if you are not using a DHCP server in your environment but are still using a TFTP server to obtain the Cisco ATA configuration file:

Procedure

Step 1 Set the DHCP parameter to 0. Step 2 Set the UseTFTP parameter to 1. Step 3 Set the Cisco ATA parameter TftpURL to the IP address or URL of the TFTP server. For more

information on setting the TftpURL parameter, see the “TftpURL” section on page 5-5.

Note If you are not using a DHCP server to provide the TFTP server location, you must manually enter

the TftpUrl using either the voice configuration menu or the Web configuration page.

Step 4 If you have done already done so, statically configure the following parameters using the voice

configuration menu (see the “Voice Configuration Menu” section on page 3-20). These are the parameters you need to configure for the Cisco ATA to obtain network connectivity:

• StaticIP

Chapter 3 Configuring the Cisco ATA for H.323

• StaticRoute

• StaticNetMask

Other parameters that are normally supplied by DHCP may be provided statically by configuring their values. These parameters are:

• DNS1IP

• DNS2IP

• NTPIP

• AltNTPIP

• Domain

This completes the parameter settings you need to configure in order for the Cisco ATA to contact the TFTP server (without using DHCP) that will contain the configuration file for the Cisco ATA.

Voice Configuration Menu

The main reasons to use the voice configuration menu are to establish IP connectivity for the Cisco ATA if a DHCP server is not being used in your network environment, and to reset the Cisco ATA to its factory values if necessary. You can also use the voice configuration menu if you need to configure a small number of parameters or if the web interface and TFTP configuration are not available.

Chapter 3 Configuring the Cisco ATA for H.323

Note Do not use the voice configuration menu to attempt to change any values that you configured by means

of the TFTP configuration file method. Whenever the Cisco ATA refreshes, it downloads its ata<macaddress> configuration file or atadefault.cfg default configuration file from the TFTP server, and the values in either of these files will overwrite the values of any corresponding parameters configured with the voice configuration menu.

See Chapter 5, “Parameters and Defaults,” for a complete list of parameters and their definitions. Also see Table 4-4 on page 4-12 for an alphabetical listing of configurable features and references to their corresponding parameters.

This section contains the following topics:

• Using the Voice Configuration Menu, page 3-21

• Entering Alphanumeric Values, page 3-22

• Resetting the Cisco ATA to Factory Default Values, page 3-23

Using the Voice Configuration Menu

Voice Configuration Menu

To manually configure the Cisco ATA by using the voice configuration menu and the telephone keypad, perform the following steps:

Procedure

Step 1 Connect an analog touch-tone phone to the port labeled Phone 1 on the back of the Cisco ATA. Step 2 Lift the handset and press the function button located on the top of the Cisco ATA. You should receive

the initial voice configuration menu voice prompt.

Step 3 Using the telephone keypad, enter the voice menu code for the parameter that you want to configure or

the command that you want to execute, then press #. For a list of voice menu codes, see Appendix B,

“Voice Menu Codes.”

Table 3-6 lists the menu options that you need to configure basic IP connectivity for the Cisco ATA, after

which you can use the Cisco ATA web configuration page to configure additional parameters.

Note If you are using the voice configuration menu to statically configure the Cisco ATA IP address,

you must disable DHCP by setting its value to 0.

Table 3-6 Parameters that Provide Basic IP Connectivity for the Cisco ATA

Voice Menu Number Features

1 StaticIP—IP address of the Cisco ATA.

2 StaticRoute—Default gateway for the Cisco ATA to use.

10 StaticNetMask—Subnet mask of the Cisco ATA.

20 DHCP—Set value to 0 to disable the use of a DHCP server; set value to 1 to enable

DHCP.

22 Review the default router for the Cisco ATA to use.

23 Review subnet mask of the Cisco ATA.

Note Use the * key to indicate a delimiter (dot). For example, to enter an IP address of 192.168.3.1,

you would enter 192*168*3*1 on your telephone keypad.

Note When entering values for a field that contains a hexadecimal value, you must convert the

hexadecimal value to a decimal value in order to enter it into the voice configuration menu system. For example, to enter the hexadecimal value 0x6A, you would enter the number 106 on the telephone keypad.

The voice configuration menu repeats the value you entered, then prompts you to press one of the following keys:

• 1=Change your entered value

• 2=Review your entered value

• 3=Save your entered value

• 4=Review the current saved value

Step 5 Cisco strongly recommends that you set a password. Use the voice menu code 7387277 (SETPASS) to

configure a password through the voice configuration menu, after which you are prompted for the password whenever you attempt to change a parameter value.

Step 6 After completing the configuration through the voice configuration menu, press the # key to exit. Step 7 Hang up the telephone. The Cisco ATA configuration refreshes. The function button fast-blinks when

the refresh completes.

Entering Alphanumeric Values

Some voice configuration menu options require you to enter alphanumeric characters. Alphanumeric entry differs from numeric entry because you must press # after each character selected.

If you need to enter an alphanumeric value, the voice prompt tells you to enter an alphanumeric value; otherwise, enter a numeric value (0 to 9).

Table 3-7 lists the keys on a telephone keypad and their respective alphanumeric characters.

Chapter 3 Configuring the Cisco ATA for H.323

You can access the web configuration page from any graphics-capable browser, such as Microsoft Internet Explorer or Netscape. This provides easy initial access to the Cisco ATA configuration within the administrator’s private network.

Follow these steps to set parameters using the web configuration page:

Procedure

Step 1 Make sure that your PC and the Cisco ATA are already networked and visible to each another. Step 2 Open your web browser. Step 3 Enter the URL for your configuration page. The default URL for the web server is:

http://IP Address/dev

For example, the configuration page for a Cisco ATA with the IP address 192.168.3.225 is:

http://192.168.3.225/dev

Step 4 Select the values for the items that you want to configure. See Chapter 5, “Parameters and Defaults,” for

a complete list of parameters and their definitions. Also see Table 4-4 on page 4-12 for an alphabetical listing of configurable features and references to their corresponding parameters.

Refreshing or Resetting the Cisco ATA

Note Cisco strongly recommends that you set a password. Use the UIPassword parameter to configure a

password, after which you are prompted for the password whenever you attempt to change a parameter value. Configuration parameters cannot be accessed through the voice configuration menu if the password contains one or more letters and can be changed only by using the web interface or the TFTP configuration method.

Step 5 Click apply to save your changes.

The Cisco ATA automatically refreshes its configuration.

Step 6 Close your web browser.

Refreshing or Resetting the Cisco ATA

Whenever you make configuration changes to your Cisco ATA configuration file, you can refresh or reset the Cisco ATA for these configuration changes to immediately take effect. If you do not refresh or reset the Cisco ATA, the configuration changes will take effect the next time the Cisco ATA contacts the TFTP server, which occurs based on the configured value of the CfgInterval parameter.

Note A refresh procedure will update the Cisco ATA configuration file. A reset procedure will also update the

Cisco ATA configuration file, and will additionally power-down and power-up the Cisco ATA. A reset should not be necessary if your only goal is to update the configuration file.

Obtaining Cisco ATA Configuration File After Failed Attempt

Procedure to Refresh the Cisco ATA

To refresh the Cisco ATA, enter the following command from your web browser:

http://<ipaddress>/refresh

where ipaddress is the IP address of the Cisco ATA that you are refreshing.

Procedure to Reset the Cisco ATA

To reset the Cisco ATA, enter the following command from your web browser:

http://<ipaddress>/reset

where ipaddress is the IP address of the Cisco ATA that you are resetting.

Obtaining Cisco ATA Configuration File After Failed Attempt

The Cisco ATA uses the following formula for determining how soon to contact the TFTP server for the Cisco ATA configuration file after a failed attempt at getting the file. The result of the formula is called the random back-off amount.

random back-off amount = CfgInterval + random(min(1800, CfgInterval))

where

• CfgInterval is the value of the CfgInterval configuration parameter (in seconds). For more

information about this parameter, see the “CfgInterval” section on page 5-6.

• random(x) function yields a value between 0 and x-1.

• min(x,y) function yields the smaller value of x and y.

Upgrading the H.323 Signaling Image

For instructions on how to upgrade the Cisco ATA to the most recent H.323 signaling image, refer to the following list:

• To use the recommended TFTP method of upgrading the Cisco ATA, see the “Upgrading the

Signaling Image from a TFTP Server” section on page 8-1.

• In the rare instance that you are not using the TFTP server to configure the Cisco ATA and to obtain

software upgrades, you must manually upgrade to the latest signaling image immediately after the Cisco ATA boots up. In this case, see the “Upgrading the Signaling Image Manually” section on

page 8-2.

Setting Up User IDs for the Cisco ATA

Each Cisco ATA can support two FXS ports. You can assign a user ID, which is usually an E.164 phone number, to each port. Use the Cisco ATA parameter UID0 to configure an ID for the Phone 1 port, and use the UID1 parameter for the user ID of the Phone 2 port.

Related Configuration Parameters

• UID0, page 5-16

• UID1, page 5-17

Using the Cisco ATA with an H.323 Gatekeeper

The Cisco ATA can function with an H.323 gatekeeper to enable Cisco ATA registration, admission, and use of directory services on an H.323 network. To use the Cisco ATA with a primary H.323 gatekeeper, you need to configure the GkOrProxy parameter with the IP address assigned to the primary H.323 gatekeeper. Optionally, you can specify the primary gatekeeper identifier using the GkId parameter if this identifier is required for the Cisco ATA to successfully register with the H.323 network.

Important Basic H.323 Services

This section contains the following topics:

• Choosing Cisco ATA Registration Mode with an H.323 Gatekeeper, page 4-3

• Setting Up Gatekeeper Time-To-Live Value, page 4-4

• Setting Up an Alternate H.323 Gatekeeper, page 4-4

• Establishing Authentication with Cisco H.323 Gatekeeper, page 4-5

Related Configuration Parameters

• GkOrProxy, page 5-13

• GkId, page 5-14

Choosing Cisco ATA Registration Mode with an H.323 Gatekeeper

The Cisco ATA can register with an H.323 gatekeeper in one of two modes:

• Single registration—Both Cisco ATA FXS ports register at the same time with the H.323

gatekeeper. This reduces gatekeeper registration traffic by 50 percent when both ports are enabled.

• Dual registration—Each FXS port registers separately with the H.323 gatekeeper.

To configure single-mode registration, you need to set the UseLoginID parameter to 1, and then configure the LoginID1 and LoginID2 parameters with identical values. The LoginID1 and LoginID2 parameters are used for the H.323 ID, whereas the UID0 and UID1 parameter values are used as E.164 phone numbers.

Related Configuration Parameter

GkTimeToLive, page 5-14

Chapter 4 Basic and Additional H.323 Services

Setting Up an Alternate H.323 Gatekeeper

To provide redundancy in systems that use an H.323 gatekeeper, the Cisco ATA allows you to either statically configure an alternate H.323 gatekeeper or dynamically assign an H.323 gatekeeper.

To enable the static alternate gatekeeper feature, you need to configure the AltGk parameter with the IP address assigned to the alternate H.323 gatekeeper. To enable the Cisco ATA to perform full gatekeeper registration when it switches to a statically configured alternate H.323 gatekeeper, configure Bit 3 of the ConnectMode parameter to the value of 1.

To enable the dynamic alternate gatekeeper feature, you need to configure the primary H.323 gatekeeper so that the list of alternate gatekeepers is included in the H.225 RAS messages that the H.323 gatekeeper sends to the Cisco ATA. The Cisco ATA can accept as many as four dynamic alternate gatekeepers configured in the H.225 RAS messages. (The Cisco ATA supports the alternate gatekeeper list in GCF/GRJ, ACF/ARJ, RCF/RRJ, and DRJ RAS messages.)

Dynamic alternate gatekeepers and static alternate gatekeepers can co-exist. When the Cisco ATA receives an alternate gatekeeper list in an H.225 RAS message, the static alternate gatekeeper is merged with the dynamic alternate gatekeepers. The static alternate gatekeeper is kept and given the lowest priority.

You can configure the AltGkTimeout parameter to specify the number of seconds the Cisco ATA should wait before it automatically switches back to the primary H.323 gatekeeper after being moved to an alternate gatekeeper. By default, the switch-back procedure is disabled (the AltGkTimeout parameter value is set to 0).

Establishing Authentication with Cisco H.323 Gatekeeper

You can configure the Cisco ATA to establish authentication with a Cisco H.323 Gatekeeper. The Cisco ATA supports two authentication methods:

• Cisco registration level-security

• Cisco admission-level security (per-call basis)

To configure either authentication method, use the following procedure:

Procedure

Step 1 Set the UseLoginID parameter to 1. This setting indicates that the LoginID0 and LoginID1 fields will

be used for Cisco ATA H.323 registration.

Step 2 Set the UID0 and UID1 parameters to the E.164 phone numbers that are assigned to the FXS ports on

the Cisco ATA.

Step 3 Set the LoginID0 and LoginID1 parameters to the H.323 ID. The H.323 ID is used when the Cisco ATA

registers with the H.323 gatekeeper. This ID is also used as the account ID for the RADIUS server.

Step 4 Set the PWD0 and PWD1 parameters to the passwords for the Phone 1 and Phone 2 FXS ports (the

passwords in the RADIUS server), respectively.

Important Basic H.323 Services

Step 5 Set the NTPIP and AltNTPIP parameters to the IP addresses of the NTP servers in your network. Step 6 Select the authentication method using the AutMethod parameter (0 indicates no authentication; 1

indicates the Cisco registration level security method; 2 indicates the Cisco admission level security method).

Note The authentication methods are Cisco Proprietary H.235 implementations, which use the Cisco

access/clear token structure rather than the VocalTec crypto token structure.

Using the Cisco ATA Without an H.323 Gatekeeper

You can use the Cisco ATA without using an H.323 gatekeeper, as this section describes with the following topics:

• Using the Cisco ATA With an H.323 Gateway but Without an H.323 Gatekeeper, page 4-6

• Using Multiple Cisco ATAs Without an H.323 Gatekeeper, page 4-6

Using the Cisco ATA With an H.323 Gateway but Without an H.323 Gatekeeper

You can use a Cisco ATA with an H.323 network that does not contain an H.323 gatekeeper. In this scenario, all calls initiated from the Cisco ATA are directed to a specified H.323 gateway. To specify this H.323 gateway, you configure its IP address using the Gateway parameter, and you disable the H.323 gatekeeper feature by setting the GkorProxy parameter to 0.

Note For all calls sent from the H.323 gateway to the Cisco ATA, the E.164 number assigned to each of the

Cisco ATA FXS ports must be included in the H.225 Setup message, either in the DestinationAddress field or the Q.931 CalledPartyNumber field. The Cisco ATA will reject the call if it cannot find its E.164 number in the H.255 Setup message.

Related Configuration Parameters

• Gateway, page 5-20

• GkOrProxy, page 5-13

Using Multiple Cisco ATAs Without an H.323 Gatekeeper

You can make calls from one Cisco ATA to another Cisco ATA in an H.323 network that does not contain an H.323 gatekeeper.

For one Cisco ATA to access a specific FXS port on another Cisco ATA, you use an IP dialing procedure. The Cisco ATA originating the call must have the following information about the destination Cisco ATA:

• E.164 phone number of the destination FXS port

• IP address of the destination Cisco ATA

To enable the IP dialing procedure, you need to set the IPDialPlan parameter to 1 to instruct the Cisco ATA to look for the destination IP address in the dialed digits.

Example

Cisco ATA X is going to initiate a call to Cisco ATA Y (with the following pertinent information):

• IP address of Cisco ATA Y—192.168.2.112.

• E.164 phone number for the Phone 1 port of Cisco ATA Y—1:5556666

• E.164 phone number for the Phone 2 port of Cisco ATA Y—2:5558888

Setting the Audio Codecs

You can configure the following codec-related settings:

• Low-bit-rate codec—When operating with a low-bit-rate codec, the Cisco ATA can support either

two G.723.1 connections or one G.729 connection. You must statically configure the selection of G.723.1 or G.729 by using the LBRCodec parameter.

When G.723.1 is the low-bit-rate codec, each FXS port is allocated one G.723.1 connection. When G.729 is used, only one FXS port can use G.729. The G.729 resource is allocated in a dynamic manner. When a call begins, the FXS port requests and takes an available G.729 resource. The Cisco ATA releases this resource when the call is completed.

Additional H.323 Services

Use Bit 1 of the AudioMode parameter to disable and enable the use of the low-bit-rate codec.

Parameters for Configuration Method and Encryption

CfgInterval

Description

Use this parameter to specify the number of seconds between each configuration update. The Cisco ATA will also upgrade its signaling image if it detects that the TFTP server contains an upgraded image.

For example, when using TFTP for configuration, the Cisco ATA contacts TFTP each time the interval expires to get its configuration file.

You can set CfgInterval to a random value to achieve random contact intervals from the Cisco ATA to the TFTP server.

Value Type

Related Parameters

• UseTFTP, page 5-4

• TftpURL, page 5-5

Description

This parameter specifies the encryption key that is used to encrypt the Cisco ATA configuration file on the TFTP server.

The cfgfmt tool, which is used to create a Cisco ATA binary configuration file (see the “Using

Encryption With the cfgfmt Tool” section on page 3-12), automatically encrypts the binary file when the

EncryptKey parameter has a value other than 0. The cfgfmt tool uses the rc4 encryption algorithm.

If this parameter value is set to 0, the Cisco ATA configuration file on the TFTP server is not encrypted.

EncryptKeyEx parameter. For more information, see the “EncryptKeyEx” section on page 5-7.

For examples on how to upgrade from the EncryptKey parameter to the stronger encryption method that uses the EncryptKeyEx parameter, see the “Examples of Upgrading to Stronger Encryption Key” section

EncryptKeyEx

Parameters for Configuration Method and Encryption

Description

This parameter specifies an encryption key that is stronger than the key specified with the EncryptKey parameter. This stronger key is used to encrypt the Cisco ATA configuration file on the TFTP server.

Note Cisco recommends using the EncrpytKeyEx parameter instead of the EncryptKey parameter for the

strongest possible encryption of the Cisco ATA configuration file.

When the EncryptKeyEx parameter is set to a non-zero value, the Cisco ATA uses this value as the encryption key and ignores any value that has been set for the EncryptKey parameter. The cfgfmt tool, which is used to create a Cisco ATA binary configuration file (see the “Using Encryption With the cfgfmt

Tool” section on page 3-12), automatically encrypts the binary file using the stronger rc4 encryption

algorithm.

When EncryptKeyEx is used for encryption, the Cisco ATA searches for the configuration file with the format ata<macaddress>.x. on the TFTP server.

If the value of the EncryptKeyEx parameter is 0, then the Cisco ATA uses the value of the EncryptKey parameter for encryption.

Note The cfgfmt tool (version 2.3) program generate an ata<macaddress>.x file in addition to an

ata<macaddress> file if the EncryptKeyEx parameter is specified. You should place both such configuration files on the TFTP server.

LBRCodec

Audio Configuration Parameters

Description

This parameter allows you to specify which low-bit-rate codecs are available. The Cisco ATA is capable of supporting two G.723.1 connections or one G.729 connection. When G.723.1 is selected as the low-bit-rate codec, each FXS port is allocated with one G.723.1 connection. When G.729 is selected, only one FXS port is capable of operating with the G.729 codec. The allocation of the G.729 resource to the FXS port is dynamic. The G.729 resource, if available, is allocated to an FXS port when a call is initiated or received; the resource is released when a call is completed.

The following values are valid:

• 0—Select G.723.1 as the low-bit-rate codec.

• 3—Select either G.729 as the low-bit-rate codec.
