THE SPECIFICATIONS AND INFORMATION REGARDING THE PRODUCTS IN THIS MANUAL ARE SUBJECT TO CHANGE WITHOUT NOTICE. ALL STATEMENTS, INFORMATION, AND RECOMMENDATIONS IN THIS MANUAL ARE BELIEVED TO BE ACCURATE BUT ARE PRESENTED WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED. USERS MUST TAKE FULL RESPONSIBILITY FOR THEIR APPLICATION OF ANY PRODUCTS.
THE SOFTWARE LICENSE AND LIMITED WARRANTY FOR THE ACCOMPANYING PRODUCT ARE SET FORTH IN THE INFORMATION PACKET THAT SHIPPED WITH THE PRODUCT AND ARE INCORPORATED HEREIN BY THIS REFERENCE. IF YOU ARE UNABLE TO LOCATE THE SOFTWARE LICENSE OR LIMITED WARRANTY, CONTACT YOUR CISCO REPRESENTATIVE FOR A COPY.
The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense.
The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation.
Modifying the equipment without Cisco’s written authorization may result in the equipment no longer complying with FCC requirements for Class A or Class B digital devices. In that event, your right to use the equipment may be limited by FCC regulations, and you may be required to correct any interference to radio or television communications at your own expense.
You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures:
• Turn the television or radio antenna until the interference stops.
• Move the equipment to one side or the other of the television or radio.
• Move the equipment farther away from the television or radio.
• Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)
Modifications to this product not authorized by Cisco Systems, Inc. could void the FCC approval and negate your authority to operate the product.
NOTWITHSTANDING ANY OTHER WARRANTY HEREIN, ALL DOCUMENT FILES AND SOFTWARE OF THESE SUPPLIERS ARE PROVIDED “AS IS” WITH ALL FAULTS. CISCO AND THE ABOVE-NAMED SUPPLIERS DISCLAIM ALL WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING, WITHOUT LIMITATION, THOSE OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT OR ARISING FROM A COURSE OF DEALING, USAGE, OR TRADE PRACTICE.
IN NO EVENT SHALL CISCO OR ITS SUPPLIERS BE LIABLE FOR ANY INDIRECT, SPECIAL, CONSEQUENTIAL, OR INCIDENTAL DAMAGES, INCLUDING, WITHOUT LIMITATION, LOST PROFITS OR LOSS OR DAMAGE TO DATA ARISING OUT OF THE USE OR INABILITY TO USE THIS MANUAL, EVEN IF CISCO OR ITS SUPPLIERS HAVE BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

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.

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).
1-4
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.

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.
OL-4008-01
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 3-7—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 3-15—This section includes information on how to obtain basic
network connectivity for the Cisco ATA and how to perform a factory reset if necessary.

Refreshing or Resetting the Cisco ATA, page 3-20—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.
Upgrading the H.323 Signaling Image, page 3-21—This section provides references to the various
means of upgrading your Cisco ATA signaling image.
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.
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.
Chapter 3 Configuring the Cisco ATA for H.323
All Cisco ATAs are shipped with a boot load 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 boot load 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 3-5 on page 3-16. 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 3-15.

Chapter 3 Configuring the Cisco ATA for H.323
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>) on the TFTP server and downloads this file if it exists.
6. If the Cisco ATA does not find the ata<macaddress> configuration file, it looks for the
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

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 3-15 for instructions on using this menu.) Also, refer to Table 3-2 for a matrix on which VLAN-related parameters and bits to configure depending on your network environment.

VLANSetting Bits 18-29
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
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.

Configuring the Cisco ATA Using a TFTP Server

Configuring the Cisco ATA Using a TFTP Server
The TFTP method of configuration is useful when you have many Cisco ATA because you can use a TFTP server for remote, batch configuration of Cisco ATAs. A TFTP server can host one unique configuration file for each Cisco ATA.
This section contains the following topics:
Setting Up the TFTP Server with Cisco ATA Software, page 3-7
Configurable Features and Related Parameters, page 3-7
Creating Unique and Common Cisco ATA Configuration Files, page 3-8
atadefault.cfg Configuration File, page 3-12
Configuring the Cisco ATA to Obtain its Configuration File from the TFTP Server, page 3-12
Setting Up the TFTP Server with Cisco ATA Software
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> or atadefault.cfg).
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.
OL-4008-01
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.
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 3-8.

Page 42
Chapter 3 Configuring the Cisco ATA for H.323
Configuring the Cisco ATA Using a TFTP Server
Note Be sure to configure the UseSIP parameter to the value of 0 (its default) to enable the H.323 protocol.
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 5,
“Parameters and Defaults,” for complete listings and descriptions of required parameters and additional
configurable features. Also, refer back to Table 3-3 on page 3-5 for all main configuration steps.
Procedure
Step 1 Use the example_uprofile.txt file as a template for creating a text file of values that are common to one
group of Cisco ATAs. The example_uprofile.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 example_uprofile.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
some parameters as follows:
ToConfig:0 UseTftp:1 DHCP:1 TFtpURL:10.10.10.1 UseSIP:0
Tip It is helpful to always include the parameter/value of ToConfig:0 in the Cisco ATA configuration
file so that every time this file is downloaded to the Cisco ATA, it will set ToConfig to 0, which the appropriate value for this parameter once the Cisco ATA has been configured. If ToConfig is 1, the Cisco ATA will continue to unnecessarily contact the TFTP server.
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).
3-8
Step 3 Save your changes.
Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide (H.323)
OL-4008-01
Page 43
Chapter 3 Configuring the Cisco ATA for H.323
Step 4 Use the example_uprofile.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 3-10. 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.
Configuring the Cisco ATA Using a TFTP Server
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 for security reasons, see the “Using the EncryptKey Parameter and cfgfmt Tool” section on page 3-11.
The syntax of the cfgfmt program follows:
Syntax
cfgfmt [-eRC4Password] -tpTagFile input-text-file output-binary-file
-eRC4Password is the optional RC 4key to encrypt the binary TFTP file provided by the cfgfmt program (up to eight alphanumeric characters).
pTagFile is the command used to specify the ptag.dat file that is provided with the Cisco ATA software version you are running. Search on the keyword ptag to find the complete name of the ptag file that is included with the Cisco ATA software for the signaling protocol you are using. Be sure this file resides in the same directory from which you are running the cfgfmt program. The ptag.dat file is used by cfgfmt.exe to format a text input representation of the parameter/value pairs to its output binary representation.input-text-file is the input text file representation of the Cisco ATA configuration file.
input-text-file is the input text file representation of the Cisco ATA configuration file.
output-binary-file is the final output binary file that Cisco ATA uses as the TFTP configuration file.

Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide (H.323)
3-9
Page 44
Configuring the Cisco ATA Using a TFTP Server
Example
cfgfmt -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 the binary configuration file in the TFTP server root directory.
When the Cisco ATA powers up, it will retrieve its unique configuration file 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 and storing the binary file 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 3-20.)
After being refreshed, the Cisco ATA will download the updated ata<macaddress> configuration file.
Chapter 3 Configuring the Cisco ATA for H.323
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.
The following command and output show an example of this command.
Command Example
atapname.exe 10.20.30.40.50.60
Command Output
3-10
ata0a141e28323c
Note The same functionality is available from the voice configuration menu (voice menu code 84#), which
will announce the Cisco ATA profile name.

OL-4008-01
Page 45
Chapter 3 Configuring the Cisco ATA for H.323
Using the EncryptKey Parameter and cfgfmt Tool
The EncryptKey parameter encrypts binary files being transferred over TFTP. You can change this key for each Cisco ATA, so that only one specific Cisco ATA can decode the information.
By default, the Cisco ATA-specific ata<macaddress> configuration file is not encrypted. If encryption is required, however, you must manually configure the EncryptKey parameter before you boot up the Cisco ATA so that the TFTP method is secure. Use either the voice configuration menu (see the “Voice
Configuration Menu” section on page 3-15) or the Cisco ATA web configuration page (see the “Cisco ATA Web Configuration Page” section on page 3-18) to configure the EncryptKey parameter.
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.
Set the EncryptKey parameter to a nonzero value. When this value is nonzero, the Cisco ATA assumes that the binary configuration file on the TFTP server is to be encrypted with this key by means of the RC4 cipher algorithm. The Cisco ATA will use this key to decrypt the configuration file.
The Cisco ATA EncryptKey parameter and the encryption key used in the cfgfmt tool command syntax must match.
Configuring the Cisco ATA Using a TFTP Server
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.
The cfgfmt.exe syntax affects how the EncryptKey parameter is used, as shown in the following examples. In these examples, input_text is the ata<macaddress>.txt file that you will convert to binary to create the ata<macaddress> configuration file for the Cisco ATA; output_binary is that binary ata<macaddress> file, and Secret is the encryption key.
Syntax examples
cfgfmt -tpTagFile 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 -eSecret -tpTagFile input-text-file output-binary-file
If the Cisco ATA EncryptKey parameter has the value of 0 or is not included in input-text-file, the Secret is used to encrypt the output-binary-file. If input-text-file sets the Cisco ATA EncryptKey parameter to a nonzero value and the -e option is used, then output-binary-file is encrypted with the EncryptKey parameter set in input-text-file and Secret is ignored.
cfgfmt -E -tpTagFile input-text-file output-binary-file
The -E (uppercase) option means that any value specified for the Cisco ATA EncryptKey parameter in input-text-file is ignored. However, because Secret is not specified in this example, output-binary-file is not encrypted. Nevertheless, the EncryptKey parameter and its value, if specified in input-file-text, will be included in output-binary-file for possible encryption at a later time.

Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide (H.323)
3-11
Page 46
Configuring the Cisco ATA Using a TFTP Server
cfgfmt -E -eSecret -tpTagFile input-text-file output-binary-file
The -E (uppercase) option means that any value specified for the Cisco ATA EncryptKey parameter in input-text-file is ignored and the output-binary-file is encrypted with the Secret key. However, the EncryptKey parameter and its value, if specified in input-text-file, will be included in output-binary-file.
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 (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.
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:
Chapter 3 Configuring the Cisco ATA for H.323
Procedure
Step 1 Make a copy of the example_uprofile.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 Be sure to name the output file atadefault.cfg.
Step 4 Store the binary atadefault.cfg 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.
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 3-13

OL-4008-01
Page 47
Chapter 3 Configuring the Cisco ATA for H.323
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 3-13
Procedure if DHCP Server is not Under Control of Cisco ATA Administrator, page 3-13
This section also includes the topic:
Other DHCP Options You Can Set, page 3-14
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
Configuring the Cisco ATA Using a TFTP Server
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 5-33).
Step 2 Make sure to use default values for the following Cisco ATA parameters:
TftpURL=0
UseTftp=1
DHCP=1
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.
Cisco ATA 186 and Cisco ATA 188 Analog Telephone Adaptor Administrator’s Guide (H.323)
OL-4008-01
3-13
Page 48
Configuring the Cisco ATA Using a TFTP Server
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 3-15.
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 3-15).
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.
Chapter 3 Configuring the Cisco ATA for H.323
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
DHCP option 43—Set this option to identify the protocol (for example, H.323)
DHCP Option 60 (DHCP_VENDOR_CLASS_ID)—Use this parameter to identify the type of
Cisco ATA box (ATA1 86 or ATA1 88 ).
Without Using a DHCP Server

Chapter 3 Configuring the Cisco ATA for H.323
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 3-15). These are the parameters you need to configure for the Cisco ATA to obtain network connectivity:
StaticIP
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

Voice Configuration Menu

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.
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.

Using the 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 3-5 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.
Chapter 3 Configuring the Cisco ATA for H.323
Table 3-5 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.
21 Review the IP address of the Cisco ATA.
22 Review the default router for the Cisco ATA to use.
23 Review subnet mask of the Cisco ATA.
Step 4 Follow the voice prompts and enter the appropriate values, then press the # key.
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.

2=Review your entered value
3=Save your entered value
4=Review the current saved value
Step 5 Press the # key after you have entered the desired key. If you do not press the # key, the system will
automatically timeout after 10 seconds.
Step 6 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 7 After completing the configuration through the voice configuration menu, press the # key to exit.
Step 8 Hang up the telephone. The Cisco ATA configuration refreshes. The function button fast-blinks when
the refresh completes.
Voice Configuration Menu
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 3-6 lists the keys on a telephone keypad and their respective alphanumeric characters.
Using Tabl e 3 - 6 as a guide, enter the appropriate number key on the telephone keypad as many times as needed to select the number, letter, or symbol required. For example, to enter 58sQ, you would enter:
5 # 8 # 7 7 7 7 7 # 7 7 7 7 7 7 7 # #

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.

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.

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.

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
4-6
E.164 phone number for the Phone 2 port of Cisco ATA Y—2:5558888
To call the Phone 1 port on Cisco ATA Y, you would dial 5556666**192*168*2*112#.
To call the Phone 2 port on Cisco ATA Y, you would dial 5558888**192*168*2*112#.

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

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:
OL-4008-01
0—Select G.723.1 as the low-bit-rate codec.
3—Select either G.729 as the low-bit-rate codec.

TimeZone
Description
This parameter is the timezone offset from Greenwich Mean Time (GMT) for time-stamping incoming calls with local time (to use for Caller ID display, for example).
Local time is generated by the following formula:
Local Time=GMT + TimeZone, if TimeZone <= 12
Local Time=GMT + TimeZone - 25, if TimeZone > 12

NTPIP, page 5-30
AltNTPIP, page 5-30
Description
This parameter is the NTP IP address, required if DHCP server does not provide one.
The Cisco ATA requires an NTP Server from which to obtain Coordinated Universal Time (UTC) to time-stamp incoming calls (H.323 and SIP) to drive an external Caller-ID device.
DHCP may also supply a NTP server. If NTPIP is specified, it overwrites the value supplied by DHCP. NTPIP is ignored if its value is 0 or 0.0.0.0.
The user must not specify a port parameter. The Cisco ATA uses the default NTP port only.
