I have just purchased a used 7960 IP phone and I need to upgrade the firmware (MGCP) to SIP.
I have tried Cisco and my local re-seller, but they wont sell me the firmware, all I can get is a quote for a new phone!
Can anyone tell me how to get hold of copies of the firmware to upgrade the old phone to the latest version of SIP. I understand from reading this group that it is a 2 or 3 stage process. It currently has a V3 image in it.
Thanks in advance
