GXW42xx User Manual 
Version 1.0.5.43 
“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. A service 
provider or  an enterprise  with large deployment of  GXW42XX can easily manage the  configuration  and 
service provisioning of individual devices remotely from a central server.  
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. At boot-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/HTTPS  server  for 
further provisioning.  
Grandstream also provides configuration tools (Windows and Linux/Unix version) to facilitate the task of 
generating  device  configuration  files.   The  Grandstream  configuration  tools  are  free  to  end  users.  The 
configuration  tools  and  configuration  templates  are  available  for  download  from
