PROVISIONING
OVERVIEW
Grandstream SIP Devices can be configured via Web interface as well as via configuration file through
TFTP or HTTP/HTTPS download. All Grandstream SIP devices support a proprietary binary format
configuration file as well as XML format configuration file. The UCM6102/UCM6104/UCM6108/UCM6116
provides a Plug and Play mechanism to auto-provision the Grandstream SIP devices in a zero configuration
manner, which 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, assignment and provisioning. The
UCM6102/UCM6104/UCM6108/UCM6116 is capable to accomplish the following configurations on the SIP
end point device.
 Assign an extension to the phone.
 Set up config server download path for further provisioning purpose.
 Set up LDAP client side configurations to use the PBX default phonebook.
This section explains how zero config works on the UCM6102/UCM6104/UCM6108/UCM6116. The
settings for this feature can be accessed via Web GUI->PBX->Basic/Call Routes->Zero Config.

network using PnP feature with multicast SUBSCRIBE/NOTIFY. All current Grandstream phones
support PnP feature and will send SUBSCRIBE at boot up and in the process be discovered by the PBX
with the same type PnP feature support.
On the phone side, after the phone boots up, it will send out multicast SUBSCRIBE message. When
the UCM6102/UCM6104/UCM6108/UCM6116 receives the SUBSCRIBE, a SIP NOTIFY message will
