Hello I have a gateway as H.323 integrated to CUCM. When someone calls from PSTN I receive "Unknown number" instead of the phone number of the caller (Caller ID missed).
In voice debugs ccapi I don't see the Caller ID, but in debug vpm I see caller ID received. Also, we did some test with an analog phone an we are able to see the Caller ID. Any suggestions?
Gateway version 15.4, 6 FXO ports, caller ID enabled and cptone MX. Telmex provider.
Kind regards,
