Page 13

Five Success Tips when using the Voice Prompt

1. “*” shifts down to the next menu option

2. “#” returns to the main menu

3. “9” functions as the ENTER key in many cases to confirm an option

4. All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP

address. For IP address should be key in like 192168000026. No decimal is needed).

5. Key entry can not be deleted but the phone may prompt error once it is detected

, add 0 before the digits if the digits are less than 3 (i.e. - 192.168.0.26

PLACING A PHONE CALL

Phone or Extension Numbers

1. Dial the number directly and wait for 4 seconds (Default “No Key Entry Timeout”); or

2. Dial the number directly and press # (Use # as dial key” must be configured in web configuration).

Examples:

1. Dial an extension directly on the same proxy, (e.g. 1008), and then press the # or wait for 4 seconds.

2. Dial an outside number (e.g. (626) 666-7890), first enter the prefix number (usually 1+ or international code) followed by the phone number. Press # or wait for 4 seconds. Check with your VoIP service provider for further details on prefix numbers.

IRECT IP CALLS

Direct IP calling allows two parties, that is, a FXS Port with an analog phone and another VoIP Device, to talk to each other in an ad hoc fashion without a SIP proxy.

Elements necessary to completing a Direct IP Call:

1. Both GXW400x and other VoIP Device, have public IP addresses, or

2. Both GXW400x and other VoIP Device are on the same LAN using private IP addresses, or

3. Both GXW400x and other VoIP Device can be connected through a router using public or private

IP addresses (with necessary port forwarding or DMZ).

GXW400x supports two ways to make Direct IP Calling:

Using IVR

1. Pick up the analog phone then access the voice menu prompt by dial “***”

2. Dial “47” to access the direct IP call menu

3. Enter the IP address after the dial tone and voice prompt “Direct IP Calling”

Using Star Code

1. Pick up the analog phone then dial “*47”

2. Enter the target IP address. Note: NO dial tone will be played between step 1 and 2.

Destination ports can be specified by using “*” (encoding for “:”) followed by the port number.

Examples:

Grandstream Networks, Inc. GXW-400x User Manual Page 13 of 39

Firmware 1.0.0.39 Last Updated: 5/2007

Page 14

a) If the target IP address is 192.168.0.160, the dialing convention is

*47 or Voice Prompt with option 47, then 192*168*0*160.

followed by pressing the “#” key if it is configured as a send key or wait 4 seconds. In this case, the default destination port 5060 is used if no port is specified

b) If the target IP address/port is 192.168.1.20:5062, then the dialing convention would be:

*47 or Voice Prompt with option 47, then 192*168*0*160*5062 followed by pressing the “#” key if it is configured as a send key or wait for 4 seconds.

NOTE: When completing direct IP call, the “Use Random Port” should set to “NO”. You can not direct IP calls between FXS1 to FXS2 since they are using same IP.

make

CALL HOLD

Place a call on hold by pressing the “flash” button on the analog phone (if the phone has that button). Press the “flash” button again to release the previously held Caller and resume conversation. If no “flash” button is available, use “hook flash” (toggle on-off hook quickly). You may drop a call using hook flash.

CALL WAITING

Call waiting tone (3 short beeps) indicates an incoming call, if the call waiting feature is enabled. Toggle between incoming call and current call by pressing the “flash” button. First call is placed on hold. Press the “flash” button to toggle betw e en two active calls.

CALL TRANSFER

Blind Transfer

Assume that call Caller A and B are in conversation. A wants to Blind Transfer B to C:

3. Caller A presses FLASH on the analog phone to hear the dial tone.

4. Caller A dials *87 then dials caller C’s number, and then # (or wait for 4 seconds)

5. Caller A will hear the confirm tone. Then, A can hang up.

NOTE: “Enable Call Feature” must be set to “Yes” in web configuration page. Caller A can place a call on hold and wait for one of three situations:

1. A quick confirmation tone (similar to call waiting tone) followed by a dial tone. This indicates the

transfer is successful (transferee has received a 200 OK from transfer target). At this point, Caller A can either hang up or make another call.

2. A quick busy tone followed by a restored call (on supported platforms only). This means the

transferee has received a 4xx response for the INVITE and we will try to recover the call. The busy tone is just to indicate to the transferor that the transfer has failed.

3. Continuous busy tone. The phone has timed out. Note: continuous busy tone does not indicate

the transfer has been successful, nor does it indicate the transfer has failed. It often means there was a failure to receive second NO TI FY – check firmware for most recent release.

Attended Transfer

Assume that Caller A and B are in conversation. Caller A wants to Attend Transfer B to C:

1. Caller A presses FLASH on the analog phone for dial tone.

2. Caller A then dials Caller C’s number followed by # (or wait for 4 seconds).

Grandstream Networks, Inc. GXW-400x User Manual Page 14 of 39

Firmware 1.0.0.39 Last Updated: 5/2007

Page 15

3. If Caller C answers the call, Caller A and Caller C are in conversation. Then A can hang up to

complete transfer.

4. If Caller C does not answer the call, Caller A can press “flash” to resume call with Caller B.

NOTE: When Attended Transfer fails and A hangs up, the GXW400x will ring back user A to remind A that B is still on the call. A can pick up the phone to resume conversation with B.

3-WAY CONFERENCING

The GXW400x supports Bellcore style 3-way Conference.

Instructions for 3-way conference:

Assuming that call party A and B are in conversation. A (GXW400x) wants to bring C in a conference:

1. A presses FLASH (on the analog phone, or Hook Flash for o ld model phones) to get a dial tone.

2. A dials C’s number then # (or wait for 4 seconds).

3. If C answers the call, then A presses FLASH to bring B, C in the conference.

4. If C does not answer the call, A can press FLASH back to talk to B.

5. If A presses FLASH during conference, C will be dropped out.

ENDING AND RECEIVING FAX

GXW–400x supports fax in two modes: 1) T.38 (Fax over IP) and 2) Fax Pass through. T.38 is the preferred method because it is more reliable and works well in most network conditions. If the service provider supports T.38, please use this method by selecting T.38 as fax mode provider does not support T.38, pass-through mode may be used. If you have problems with sending or receiving Fax, toggle the Fax Tone Detection Mode setting.

Enter a STUN Server IP (or FQDN) that you may have, or look up a free public STUN Server on the internet and enter it on this field. If using Public IP, keep this field blank.

2. Use Random Ports (under Advanced Settings webpage) It really depends on your network settings, so set this parameter to Yes or No, whichever works. Generally if you have multiple IP devices under the same network, it should be set to Yes. If using a Public IP address, set this parameter to No

3. NAT Traversal (under the Profile web pages) Set this to Yes

DTMF Methods

DTMF Settings are in Profile pages.

• DTMF in-audio

• DTMF via RTP (RFC2833)

• DTMF via SIP INFO

Enable one or more DTMF methods based on your PBX system.

Preferred VOCODER (Codec)

The GXW–400x supports a broad range of voice codecs. Under Profile web pages, choose your preferred order of different codecs:

• PCMU/A (or G711µ/a)

• G729 A/B/E

• G723

• G726 (16/24/32/40)

• iLBC

User can select UDP or TCP or TLS. Please make sure you’re SIP Server or network environment supports SIP over the selected transport method. Default is UDP.

This parameter defines whether the GXW–400x NAT traversal mechanism is activated or not. If activated (by choosing “Yes”) and a STUN server is also specified, then the GXW–400x performs according to the STUN client specification. Under this mode, the embedded STUN client will detect if and what type of firewall/NAT is being used. If the detected NAT is a Full Cone, Restricted Cone, or a Port-Restricted Cone, the GXW–400x will use its mapped public IP address and port in all of its SIP and SDP messages.

If the NAT Traversal field is set to “Yes” with no specified STUN server, the GXW– 400x will periodically (every 20 seconds or so) send a blank UDP packet (with no payload data) to the SIP server to keep the “hole” on the NAT open.

Default is No. If set to “Yes” the client will use DNS SRV to look up server. If the GXW–400x has an assigned PSTN telephone number, this field should be set

to “Yes”. Otherwise, set it to “No”. If “Yes” is set, a “user=phone” parameter will be attached to the “From” header in SIP request.

This parameter controls whether the GXW–400x needs to send REGISTER messages to the proxy server. The default setting is “Yes”.

Default is No. If set to “Yes”, the SIP user’s registration information is cleared on reboot.

ONFIGURATION THROUGH A CENTRAL SERVER

Grandstream GXW-400xs can be automatically configured from a central provisioning system. When GXW-400x boot up, it will send TFTP or HTTP request to download configuration file,

“cfg000b82xxxxxx”, where “000b82xxxxxx” is the LAN side MAC address of the GXW-400x. The configuration files can be downloaded via TFTP or HTTP from the central server. A service provider

or an enterprise with large deployment of GXW-400x can easily manage the configuration and service provisioning of individual devices remotely from a central server.

Grandstream provides a licensed provisioning system called GAPS that can be used to support automated configuration of GXW-400x. GAPS (Grandstream Automated Provisioning System) uses enhanced (NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each individual GXW-400x for firmware upgrade, remote reboot, etc.

Grandstream provide GAPS (Grandstream Automated Provisioning System) service to VoIP service providers. It could be either simple redirection or with certain special provisioning settings. Initially upon booting up, Grandstream devices by default point to Grandstream provisioning server GAPS, based on the unique MAC address of each device, GAPS provision the devices with redirection settings so that they will be redirected to customer’s TFTP or HTTP server for further provisioning. Grandstream also provide GAPSLite software package which contains our NAT friendly TFTP server and a configuration tool to facilitate the task of generating device configuration files.

The GAPSLite configuration tool is now free to end users. The tool and configuration template are available for download from http://www.grandstream.com/configurationtool.html

Software Upgrade

Software upgrade can be done via either TFTP o r HTTP. The corresponding configuration se ttings are in the ADVANCED SETTINGS configuration page.

FIRMWARE UPGRADE THROUGH TFTP/HTTP

To upgrade via TFTP or HTTP, the “Firmware Upgrade and Provision ing upgrade via” field needs to be set to TFTP or HTTP, respectively. “Firmware Server Pa th” needs to be set to a valid URL of a TFTP or HTTP server, server name can be in either FQDN or IP a ddress forma t. Here are examp les of some valid URL. e.g. firmware.mycompany.com:6688/Gran dstre am/ 1.0.0.34

e.g. 168.75.215.189

NOTES:

• TFTP server in IP address format can be configured via IVR. Please refer to section

CONFIGURATION GUIDE for instructions. If TFTP server is in FQ DN format, it must be set via web configuration interface.

• End users recommended using our TFTP server. Its address can be found at

http://www.grandstream.com/firmware.html

upgraded from has an IP address 168.75.215.189. For companies, we recommend to maintain their own TFTP/ HTTP server for upgrade and provisioning procedures.

• Once a “Firmware Server Path” is set, user needs to update the settings and reboot the de vice. If

the configured firmware server is found and a new code image is a vailable, the GXW400x will attempt to retrieve the new image files by do wnloading them into the GXW400x’s SRAM. During this stage, the GXW400x’s LEDs will blink until the checking/downloading process is completed. Upon verification of checksum, the new code image will then be saved into the Flash. If TFTP/HTTP fails for any reason (e.g., TFTP/HTTP server is not responding, the re are no code image files available for upgrade, or checksum test fails, etc), the HT ATA will stop the TFTP/HTTP process and simply boot using the existing code image in the flash.

• Firmware upgrade may take as long as 1 to 20 minutes over Internet, or just 20+ seconds if it is

performed on a LAN. It is recommended to conduct firmware upgrade in a controlled LAN environment if possible. For users who do not have a local firmware upgrade server, Grandstream provides a NAT-friendly TFTP server on the public Internet for firmware upgrade. Please check the Services section of Grandstream’s Web site to obtain our public TFTP server’s IP address.

• Alternatively, user can download a free TFTP or HTTP server and conduct local firmware

upgrade. A free windows version TFTP server is available for download from

http://support.solarwinds.net/updates/New-customerFree.cfm

downloaded from http://www.grandstream.com/y-firmware.htm. Directions: Unzip the file and put all of them under the root directory of the TFTP server.

Put the PC running the TFTP server and the GXW400X device in the same LAN segment. Please go to File -> Configure -> Security to change the TFTP server's default setting from "Receive Only" to "Transmit Only" for the firmware upgrade. Start the TFTP server, in the phone’s web configuration page Configure the Firmware Server Path with the IP address of the PC Update the change and reboot the unit

ONFIGURATION FILE DOWNLOAD

Grandstream SIP Device can be configured via Web Inter face as well as via Configuration File through TFTP or HTTP. “Config Server Path” is the TFTP or HTTP server path for configura tion file. It nee ds to be set to a valid URL, either in FQDN or IP address format. The “Config Server Path” can be same or different from the “Firmware Server Path”.

A configuration parameter is associated with each particular field in the web configuration page. A parameter consists of a Capital letter P and 2 to 3 (Co uld be extended to 4 in the future) digit numeric numbers. i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page. For a detailed parameter list, please refer to the corresponding firmware release configuration template.

When Grandstream Device boots up or reboots, it will issue request for configuration file named “cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the LAN side MAC address of the device, i.e., “cfg000b820102ab”. The configuration file name should be in lower cases.

FIRMWARE AND CONFIGURATION FILE PREFIX AND POSTFIX

Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix and Postfix. This makes it the possible to store ALL of the firmware with different version in one single directory. Similarly, Config File Prefix and Postfix allows device to download the configuration file with the matching Prefix and Postfix. Thus multiple configuration files for the same device can be stored in one directory.

In addition, when the field “Check New Firmware only when F/W pre/suffix changes” is set to “Yes”, the device will only issue firmware upgrade request if there are changes in the firmware Prefix or Postfix.

ANAGING FIRMWARE AND CONFIGURATION FILE DOWNLOAD

When “Automatic Upgrade” is set to “Yes”, Service Provider can use P193 to have the devices periodically check with either Firmware Server or Config Server, whenever they are defined. This allows the device periodically check if there are any new changes need to be taken.

the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). The basic steps involved in originating an IP Telephony call are conversion of the analog voice signal to digital format and compression/translation of the signal into Internet protocol (IP) packets for transmission over the Internet or other packet-switched networks; the process is reversed at the receiving end. The terms IP Telephony and Internet Telephony are often used to mean the same; however, they are not 100 per cent interchangeable, since Internet is only a subcase of packet-switched networks. For users who have free or fixed-price Internet access, IP Telephony software essentially provides free telephone calls anywhere in the world. However, the challenge of IP Telephony is maintaining the quality of service expected by subscribers. Session border controllers resolve this issue by providing quality assurance comparable to legacy telephone systems.
