A  configuration  parameter  is  associated  with  each  particular  field  in  the  web  configuration  page.  A 
parameter consists of a Capital letter P and 2 to 5 digit numeric numbers. i.e., P2 is associated with the 
"New Password" in the Web GUI->Maintenance->Web Access page->Admin Password. For  a detailed 
parameter list, please refer to the corresponding configuration template. 
 
When the GXP2130/GXP2140/GXP2160/GXP2170/GXP2135 boots up or reboots, it will issue a request to 
download  a  configuration  file  named  "cfgxxxxxxxxxxxx"  followed  by  an  XML  file  named 
"cfgxxxxxxxxxxxx.xml", where "xxxxxxxxxxxx" is the MAC address of the phone, i.e., "cfg000b820102ab" 
and "cfg000b820102ab.xml". If the download of "cfgxxxxxxxxxxxx.xml" file is not successful, the phone will 
issue a request to download a specific model configuration file “cfg<model>.xml”, where <model> is the 
phone model, i.e.,  “cfggxp2130.xml”  for  the  GXP2130,  “cfgxp2170”  for  the  GXP2170.  If  this  file  is  not 
available, the phone will issue a request to download the generic “cfg.xml” file. The configuration file name 
should be in lower case letters.

No Touch Provisioning 
After  the  phone  sends,  config  file  request  to  the  Broadsoft  provisioning  server  via  HTTP/HTTPS,  if  the 
provisioning server responds “401 Unauthorized” asking for authentication, the phone’s LCD will prompt a 
window for user to enter username and password. Once correct username and password are entered, the 
phone will send config file request again with authentication. Then the phone will receive the config file to 
download and get provisioned automatically.   
 
Besides manually entering the username and password in LCD prompt, users can save the login credentials 
for  provisioning  process  as  well.  The  username  and  password  configuration  is  under  phone’s  web 
UI->Maintenance->Upgrade  and  provisioning  page:  “HTTP/HTTPS  Username”  and  “HTTP/HTTPS 
Password”. If the saved username and password saved are correct, login window will be skipped. Otherwise, 
login window will be popped up to prompt users to enter correct username and password again.
