PROVISIONING 
Overview 
 
Grandstream  SIP  Devices  can  be  configured  via  Web  interface  as  well  as  via  configuration  file  through 
TFTP/HTTP/HTTPS download. All Grandstream SIP devices support a proprietary binary format configuration 
file and XML format configuration file. The UCM6200 provides a Plug and Play mechanism to auto-provision the 
Grandstream SIP devices in a zero configuration manner by generating XML config file and having the phone to 
download it within LAN area. This allows users to finish the installation with ease and start using the SIP devices 
in a managed way. 
 
To  provision  a  phone,  three  steps  are  involved,  i.e.,  discovery,  configuration  and  provisioning.  This  section 
explains how Zero Config works on the UCM6200. The settings for this feature can be accessed via Web UI-
>PBX->Zero Config. 
 
Configuration Architecture for End Point Device 
 
Started  from  firmware  version  1.0.7.10,  the  end  point  device  configuration  in  zero  config  is  divided  into  the 
following three layers with priority from the lowest to the highest: 
 
  Global 
This is the lowest layer. Users can configure the most basic options that could apply to all Grandstream SIP 
devices during provisioning via Zero config. 
 
  Model 
In this layer, users can define model-specific options for the configuration template. 
 
  Device   
This  is  the  highest  layer.  Users  can  configure  device-specific  options  for  the  configuration  for  individual 
device here. 
 
Each layer also has its own structure in different levels. Please see figure below. The details for each layer are 
explained in sections [Global configuration], [Model configuration] and [Device Configuration].
