GXW42XX LCD Menu The GXW42XX gateway series includes a small LCD screen for the display of basic information. The LCD has a display area of 128x32 pixels, which will allow for 2 lines of text with a 16px height limitation per line. The LCD menu is showed as Figure 3: LCD Menu. Menu is navigated by the Down-arrow and OK button. Figure 3: LCD Menu GXW42xx User Manual Version 1.0.5.
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 which is connected to device’s FXS port.
013 Firmware 014 015 Server IP Announces current Firmware Server IP address. Enter 12- Address digit new IP address. Configuration Server IP Announces current Config Server Path IP address. Enter Address 12-digit new IP address. Upgrade Protocol Upgrade protocol for firmware and configuration update. Enter “9” to toggle between TFTP and HTTP 016 Firmware Version Firmware version information. 017 Firmware Upgrade Firmware upgrade mode.
Placing a Phone Call Phone or Extension Numbers 1. Dial the number directly and wait for 4 seconds (To change the default value, modify the following setting - “No Key Entry Timeout”) 2. Or, you may dial the number directly and press # (Use # as dial key” must be configured in web configuration). 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.
Examples: a) If the target IP address is 192.168.0.160, the dialing convention is *47 or Voice Prompt with option 047, 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.
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.
active in that Hunting Group. The number of hunting groups is limited by the number of ports each GXW model has - i.e. each port can be its own Hunting Group. The most practical and efficient way to use Hunting Groups is to assign 2 or 3 ports to separate Hunting Groups. 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 42xxports configured as a Hunting Group.
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.
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. If the service provider supports T.38, please use this method by selecting T.38 as fax mode (default). If the service 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.
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 (G726-r40), *027201 (iLBC) *03 Disable LEC (pe call) Dial “*03” +” number”. No dial tone is played in the middle.
*78 Enable Do Not Disturb (DND): When enabled all incoming calls will be rejected. *79 Disable Do Not Disturb (DND): When disabled, incoming calls will be accepted. *87 Blind Transfer *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.

and 911 Note: In some cases user wishes to dial strings such as *123 to activate voice mail or other application provided by service provider. In this case * should be predefined inside dial plan feature and the Dial Plan will be: { [x*]+}. Use # as Dial Key Allows users to configure the “#” key as the “Send” (or “Dial”) key. If set to “Yes”, “#” will send the number. In this case, this key is essentially equivalent to the “Dial” key. If set to “No”, this “#” key can be included as part of number.

System Ring Tone is used for all other calls. When selected but no Caller ID is configured, the selected ring tone will be used for all incoming calls using the FXS port. Distinctive ring tones can be configured not only for matching a whole number, but also for matching prefixes.
Name Any name to identify this specific user. Profile Select the corresponding Profile ID (1/2/3/4) Enable FXS Enable or disable the FXS port. (TR-069) Advanced Port Settings Offhook Auto-dial Configure an auto dial number when Offhook. Hunting Group Assign this port to a certain hunting group Request URI Routing ID If configured, device will route the incoming call to designated port by request URI user ID in SIP INVITE.
“cfg000b82xxxxxx” and “cfg00082xxxxxx.xml”, where “000b82xxxxxx” is the LAN MAC address of the GXW42XX . If the download of “cfgxxxxxxxxxxxx.xml” is not successful, the provision program will issue request a generic configuration file “cfg.xml”. Configuration file name should be in lower case letters. The configuration data can be downloaded via TFTP or HTTP/HTTPS from the central server.
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://www.solarwinds.com/products/freetools/free_tftp_server.aspx.
Note: 1. The Only acceptable Config file formats to be used when provisioning are XML or binary. 2. Make sure the MAC header on the Config file is the provisioned device’s MAC address or you can remove the header completely. 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.
RESTORE FACTORY DEFAULT SETTING Factory Reset WARNING! Restoring the Factory Default Setting will DELETE all configuration information of the phone. Please BACKUP or PRINT out all the settings before you approach to following steps. Grandstream will not take any responsibility if you lose all the parameters of setting and cannot connect to your VoIP service provider. There are two (2) methods for resetting your unit: Reset Button Reset default factory settings following these four (4) steps: 1.
