BASIC OPERATIONS UNDERSTANDING GXW VOICE PROMPTS GXW42XX has a built-in voice prompt menu for simple device configuration. To enter the voice prompt menu, press *** on the standard analog phone connected to any FXS port.
“9” to toggle between TFTP and HTTP 016 Firmware Version Firmware version information. 017 Firmware Upgrade Firmware upgrade mode. Enter “9” to rotate among the following three options: 047 “Direct IP Calling” 1. always check 2. check when pre/suffix changes 3. never upgrade Enter the target IP address to make a direct IP call, after dial tone. (See “Make a Direct IP Call”.
Examples: 1. Dial a 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. DIRECT 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.
*47 or Voice Prompt with option 047, then 192*168*0*160*5062 followed by pressing the “#” key if it is configured as a send key or wait for 4 seconds. 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.
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). 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.
One additional and popular way to use the Hunting Group feature is called “multiplexed analog lines”. In this configuration, a legacy PBX system with 8 FXO trunks can be connected to 8 GXW 42xx ports configured as a Hunting Group. The GXW can be registered to a SIP server provider using only one phone number. If the SIP service provider allows multiple calls to the same number, the GXW will allow 8 concurrent calls to the same SIP number.
8 is required to indicate that the SIP account tied to port marked as “Active” will be used for all members of the same Hunting group. Needless to say, those members of the same Hunting group may not be sequential ports. In following example ports 3, 5 and 7 tied to SIP Account configured in Port #1 marked as “Active”, and ports 4,6,8 tied to SIP Account configured in Port #2 marked as “Active” as well.
For example, on the GXW42xx inter-port calling is achieved by dialing *** and 7 plus two extra digits corresponding to the port number. For example the user connected to port 1 can be reached by dialing *** and 701; the user connected to port 24 can be reached by dialing *** 724. SENDING AND RECEIVING FAX GXW42XX 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.
CALL FEATURES GXW42XX supports the traditional telephony features available in a PBX as well as additional advanced telephony features. TABLE 6: CALL FEATURES TABLE (STAR CODE) Key Call Features *02 Forcing a Codec (per call) *027110 (PCMU), *027111 (PCMA), *02723 (G723), *02729 (G729), *0272616 (G726-r16), *0272624 (G724-r24), *0272632 (G726-r32), *0272640 (G726r40), *027201 (iLBC) *03 Disable LEC (pe call) Dial “*03” + ” number ”. No dial tone is played in the middle.
*90 Busy Call Forward: Dial “*90” and then the forwarding number followed by “#”. Wait for dial tone then hang up. *91 Cancel Busy Call Forward: dial “*91”. Wait for dial tone. Hang up. *92 Delayed Call Forward: Dial “*92” and then the forwarding number followed by “#”. Wait for dial tone then hang up. *93 Cancel Delayed Call Forward: Dial “*93” for a dial tone, then hang up. Flash/Hook If user hears call waiting beep, flash/hook will switch to the new incoming call.

Grandstream provides a central provisioning system GAPS (Grandstream Automated Provisioning System) to support automated configuration of Grandstream devices. GAPS uses enhanced (NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each individual Grandstream device for firmware upgrade, remote reboot, etc. Grandstream provides GAPS service to VoIP service providers. Use GAPS for either simple redirection or with certain special provisioning settings.
SOFTWARE UPGRADE Software upgrade can be done via either TFTP or HTTP/HTTPS. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page. FIRMWARE UPGRADE THROUGH TFTP/HTTP/HTTPS To upgrade via TFTP or HTTP/HTTPS, the “Firmware Upgrade and Provisioning upgrade via” field needs to be set to TFTP HTTP or HTTPS, respectively. “Firmware Server Path” needs to be set to a valid URL of a TFTP or HTTP server, server name can be in either FQDN or IP address format.
Grandstream’s latest firmware is available http://www.grandstream.com/support/firmware . Oversea users are strongly recommended to download the binary files and upgrade firmware locally in a controlled LAN environment. 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.
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 possible to store ALL of the firmwares 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.
