Re: MGCP Gateway Unregistered

Do you have the actual circuit plugged in? It will show unregistered until it detects carrier detect.

Re: MGCP Gateway Unregistered

Hi, it looks like the gateway name defined in CUCM is different to the host name of the voice gateway. Please change it and see if the MGCP gateway will register.

Re: MGCP Gateway Unregistered

Please try to use

no ip domain name

on the global configuration of the MGCP GW
