
SIP SUBSCRIBE
When the phone boots up, it sends out SUBSCRIBE to a multicast IP address in the LAN. The
UCM6200 discovers it and then sends a NOTIFY with the XML config file URL in the message body.
The phone will then use the path to download the config file generated in the UCM6200 and take the
new configuration.

DHCP OPTION 66
Route mode need to be set to use this feature. When the phone restarts (by default DHCP Option 66
is turned on), it will send out a DHCP DISCOVER request. The UCM6200 receives it and returns DHCP
OFFER with the config server path URL in Option 66, for example, https://192.168.2.1:8089/zccgi/. The
phone will then use the path to download the config file generated in the UCM6200.

mDNS
When the phone boots up, it sends out mDNS query to get the TFTP server address. The UCM6200
will respond with its own address. The phone will then send TFTP request to download the XML config
file from the UCM6200.
To start the auto provisioning process, under Web GUI->PBX->Zero Config->Zero Config Settings, fill in
the auto provision information.
