I'm trying to configure an IAD2431 to register to CUCM 6.1 using MGCP. I have entered all of the MGCP commands and enabled 'mgcpapp' on the voice ports. I configured the gateway in CUCM as well, but it's not registering. I confirmed that the hostname and domain name on the IAD match CUCM. When I configure the IAD2431 in CUCM, I choose 8FXS as the option. I notice that the ports in CUCM are labeled 1/1-1/8. However, the FXS ports on the IAD2431 are 2/0-2/7. I see that an IAD2435 is also labeled as ports 2/0-2/7. Is this the issue and is this device compatible with CUCM 6.1? I wasn't able to find a hardware support matrix for 6.1. Thanks.
