As part of my big changes today, I am also trying to add a pair of 9971 video phones to my 2851 (IOS 15.1-4) router. I tried following the directions from Cisco http://www.cisco.com/c/en/us/support/docs/voice-unified-communications/sip-ip-phone-software/113048-reg-9971ip-cucm.html#sip1
The phones seems to register but has a number of 1026, no idea where it got that. It has a dial tone but pressing any digit get instant fast busy. What am I configuring wrong?
Two other questions, do I need to configure anything special to use video? How do I put a dn from the SCCP side onto the SIP phone? I have a few intercom dn's set up on the SCCP side and need them on the buttons on the SIP phone.
This is my first attempt at working with a SIP phone, sorry for the layman questions.
Thank You,
Michael
