I believe that 7902G doesn't support SIP. The cheapest model with SIP is 
7905G, it works like a charm with SER in our lab. Really sweet and very 
well designed phone.

Please note that by default it comes with Call Manager firmware, and it 
is not very easy to upgrade to SIP, as in default configuration it has 
web-interface locked out and the only way to change firmware to a SIP 
one is to use bootp+tftp server. Also, when ordering phone make sure to 
order 48V DC power supply for it, by default it comes without one, as it 
is designed to use power-over-ethernet available on Cisco Catalyst 
switches (unless of course you are planning to connect it to such switch).
