Appreciate any suggestions and/or direction on how to begin to troubleshoot this error for an FXS port in CUCM for a Cisco C8300 router with a 24 port FXS module installed:

Product Cisco MGCP FXS Port
Gateway aaa-bbb-vg.net.xxx.com
Device Protocol Analog Access
Device is not trusted Device is not trusted
Registration: Rejected
IPv4 Address: 10.216.2.48
End-Point Name Required Field AALN/S1/SU0/1@aaa-bbb-vg.net.xxx.com

Hi Nithin,

Thanks for responding. The problem, we believe, is with these new C8300 routers that in Call Manager, two gateways needs to be configured. One with MGCP for the router itself and if it has a NIM module installed the PRI and/or POTs line configurations. Secondly, if a 24 port FXS module is installed, that it needs to be configured via SCCP as a new/secondary router in CUCM. Do you know in the drop downs, what device we should choose when attempting to add this 24 port FXS module in Call Manager under add gateway?

Thanks,
Tom
