
SIP SUBSCRIBE
When the phone boots up, it sends out SUBSCRIBE to a multicast IP address in the LAN. The
UCM6510 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 UCM6510 and take the
new configuration.

DHCP OPTION 66
This method should be used only when the UCM6510 is set to "Route" mode under web
GUI->Settings->Network Settings->Basic Settings: Method. When the phone restarts (by default
DHCP Option 66 is turned on), it will send out a DHCP DISCOVER request. The UCM6510 receives it
and returns DHCP OFFER with the config server path URL in the 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 UCM6510.
To start the auto provisioning process, under Web GUI->PBX->Zero Config->Zero Config Settings, fill in
the auto provision information.
Firmware Version 1.0.10.39
