I have a Cisco 8945 IP Phone with SCCP firmware. I like to convert it to SIP firmware. I don't have Call Manager but TFTP loaded with SIP firmware for the 8945.
I tried to reset the phone to boot up and connect to TFTP server but it keeps coming backup with SCCP load.
Unike the 7900 series it seems its almost impossible to erase the SCCP firmware and load SIP.
Does anyone have the methodology of converting the SCCP phone to SIP?
