Dear Pros,

I have a situation and need your helps:

We have a C2800 router running as voice gateway, the connection to PSTN is via some FXO ports, the voice gateway is configured as an MGCP gateway in CCM. Things worked well except the CLID (calling line id): the ip phone couldnot show the calling numbers of the PSTN callers.

Is there difference between H.323 gateways and MGCP gateway in term of CLID? And how can we deal with this?

Thanks,

hoanghiep

MGCP can not pass CLID from FXO ports. You will have to configure it with H323 for that to work properly.
