To address these requirements, Grandstream and SipXecs also support phone provisioning via HTTP protocol.  To use this capability (with SipXecs 4.6+) simply access the web based Grandstream Multimedia Phone Administration Interface (GXV3140 and GXV3175);  go to the Maintenance tab; and the Upgrade section and  set the following:

HTTP/HTTPS User Name :  PlcmSpIp

HTTP/HTTPS Password : PlcmSpIp

Upgrade Via : HTTP

Firmware Server Path : <SIPXSERVER>/phoneprov

Config Server Path :  <SIPXSERVER>/phoneprov

 Then save the configuration and reboot the phone.  The phone will reboot and download any firmware upgrade you have stored at the server as well as any configuration created for it at the configuration server.  If the phone was not previously provisioned in SipXecs, it will be automatically provisioned with a temporary ID.  You can then go back into the configuration and assign lines to the phone device and send the updated profiles to the phone.  The phone will restart after the new configuration has been downloaded and should render the new configuration accordingly.
