I don't remember if I had this same problem with a 7961G but I did
figure out that you can not do an upgrade from factory default SCCP to
the latest SIP 8.x.x firmware. In my case the phone just did not work
properly. To make it work I downgraded the phone back to SIP 7.x
firmware (iirc I used 7.5) and then upgraded to the latest SIP 8.x.x
firmware.

Hope this helps.
