Known Issues

  • It always queries the provisioning configuration file using the MAC address associated to the LAN interface even when only the WAN interface is plugged to the network;
  • it is not possible to use a sub path when using provisioning via UDP, you can only specify an IP address or an host name;

Configuration Tips

  • DHCP Server on the LAN port can be enabled/disabled with option P5001 (# Enable LAN DHCP. 0 - No, 1 - Yes)
  • Details for all options can be found in the configuration template: config-template.zip
  • To see all config fields without the template, log into the web gui and view the HTML page source (CTRL-U in Firefox)
  • When naming config files for provisioning, use the MAC address printed on the label on the bottom of the device (same as the one on the box)
  • Serial settings for console port: 115,200bps, 8,N,1, flow control off

333How to enable *xx features by-pass in GXW-4008

by mvini, Thursday 19 of July, 2007 [03:11:21 UTC]
To enable *xx, just put this string in GXW dialplan: {*xx | x+ }.
It should work fine!
Don't forget to put Enable Call Features to NO.

333Dead GXW4008 after Firmware Upgrade

by jaiume, Saturday 09 of June, 2007 [22:12:34 UTC]
I tried to upgrade my GXW-4008 firmware with 1.0.0.44, but when it rebooted, the status page showed the program file was unknown, then after another reboot, the box only has the power light on and all ports are dead. FXS ports & Both ethernet ports.

The firmware is obviously corrupted, does anyone know how to recover one of these boxes for a firware upgrade failure?

333Re: New Firmware introduces problems with *xx features

Set the dial plan item to { x*#+ } (and make sure local feature codes are disabled) and any number including *xx codes get through correctly.

333New Firmware introduces problems with *xx features

by mbuckaway, Thursday 01 of February, 2007 [20:01:11 UTC]
I updated, from the Grandstream Beta site, the firmware of my GXW4008 to 1.0.0.34 in attempts to see is early dial would work. While the firmware update did not solve that problem, it introduced a new one: I could no longer dial *xx feature codes to my Asterisk PBX. I had local feature codes disable. It turns out that Grandstream added a new "feature" to the profile called DialPlan that supports defining what is acceptable to dial from an attached phone. The default is { x+ } which means that it can only accept phone numbers starting with phone numbers!!


I recieved the following from tech support on the proper use of the dial plan "feature":


Dialplan Notes :
  • 1 Accept Digits: 1,2,3,4,5,6,7,8,9,0,*,#


  • 2 Grammar: x - any digit from 0-9;
   xx+ - at least 2 digit number; 
   
- exclude;  
   3-5 - any digit of 3, 4, or 5;  
 147 - any digit 1, 4, or 7;  
 <2=011> - replace digit 2 with 011 when dialing  


*3 Example 1: {36911 | 1617xxxxxxx} - Allow 311, 611, 911, and  
 any 10 digit numbers of leading digits 1617  

   Example 2: {
1900x+ | <=1617>xxxxxxx} - Block any number of leading digits 1900 and  
 add prefix 1617 for any dialed 7 digit numbers  

   Example 3: {1xxx2-9xxxxxx | <2=011>x+} - Allow any length of number with leading digit 2 and 10 digit-numbers of leading digit 1 and leading exchange number between 2 and 9;  
 If leading digit is 2, replace leading digit 2 with 011 before dialing
