im having a big issue with my new 4451-x not registering on the cucm , it is stuck on registering ? under cucm i added as 4451 mgcp gateway , is 4451 different than 4451-x and that is why it is not getting added?
i already did
ccm-manager config server
Solved! Go to Solution.
run a "show ccm-manager" command on your MGCP gateway and check this field in the output "MGCP Domain Name":
This name should match with the hostname on your CUCM, also do you have any firewall/Access lists in between CUCM and the gateway if so, check whtether the required ports are open ?
