Registering a 3945 VG in CUCM 8.6 using MGCP

I have also created the gateway in CallManager with the hostname.domain where it asks for the domain name. I cannot figure out why this voice gateway is not registering in CM. Any help would be greatly appreciated!

Here is my config on the VG:

I dont see any ip domain name command on your VG. Hence you should only use the hostname of the gateway in cucm without any domain name. You should only use domain name if you have ip domain name configured.

So I suggest you remove the .domain name on cucm and leave only the hostname. Then on the voice gateway do a no mgcp and then mgcp.

I tried removing the .domain in CUCM, and entering mgcp / no mgcp on the gateway. Unfortunately this did not solve the problem. Thank you for your input.

Looking closer at your debug isdn q931, I can see that layer 1 is deactivated. This suggests a physical layer issue, cabling etc. Can you check that...
