I can have my Cisco IP Communicator auto-registered within rave28 network. Are you using physical IP Phones for your testing? Have you tried to point the CUCM to 10.10.20.1 other than hq-cucm-pub?
Yes i am using physical phones, currently an 8861 and a 9971. What FREEABCGROUP did you use (I'm taking a guess at 35, but I'm not sure). My router is configured to point at 10.10.20.1 so unless there is another setting I've not come across in the past I'm stumped.
I believe this case has been answered. Can you confirm that you are good now?
yes this case is resolved, I had the wrong FREEABCGROUP, I should have been targeting 34 not 35.
I've got a collaboration 10.5 lab booked for the next few days, but no matter what i try my phones won't register. The messages i'm getting are
DNS unknown IPv4 hot hq-cucm-pub.
VPN not configured.
I've enabled auto registration which usually gets things going but not this time.
