Figure 59: UCM630xA Zero Config
SIP SUBSCRIBE
When the phone boots up, it sends out SUBSCRIBE to a multicast IP address in the LAN. The UCM630xA
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 UCM630xA and take the new configuration.
DHCP OPTION 66
Route mode needs 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 UCM630xA 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 UCM630xA.
mDNS
When the phone boots up, it sends out mDNS query to get the TFTP server address. The UCM630xA will
respond with its own address. The phone will then send TFTP request to download the XML config file from
the
UCM630xA.
