Calling ID is Unknown Number - Incoming Calls

Dears,

I have MGCP gateway, it has Vic2-4FXO , one FXO ports has analog line that is connected to Telular, the Incoming calls to an IP phone through this port shows Unknown Number for the Calling ID, I tried to change the related service parameters related to the calling ID, with no luck.

The debug voice ccapi in out at the gateway shows that the calling ID received , but when call arrives the IP phone the calling ID shows as unknown number

Any Idea

MGCP does not suppoer caller ID.

Use instead, H.323, or SIP.

Caller ID does not work on FXO ports. This is because caller ID is not supported with FXO ports when configured for MGCP. Instead, configure the gateway in H.323 mode
