Has anyone out there running SCCP and SIP IP Phone in one cluster. I have SIP IP Phone but now trying to add a single 7965 SCCP IP Phone and it refuses to register. CCM is 6.1.2
The phone just say registering on the screen. Checked CUCM and it say "unknown". Phone got IP address and TFTP correct. Firmware is confirmed to run SCCP. On firewall confirmed that SCCP is open for TCP 2000.
Thanks
