[cisco-voip] Caller ID restrictions and Unity Connection

[Eric Pedersen]

Is there a way to get calls to Unity Connection to obey calling line ID presentation restrictions? We're setting a dummy calling number of 999-999-9999 on our gateways (SIP) for calls coming in on our PRIs with no calling number. I did this because we need to filter calls in CUCM based on calling number, and the SIP gateways by default seem to set the caller to "anonymous" when there is no calling number. Without the gateway translation to set this dummy number, these calls were not making it through the calling number translation patterns.

On the matching calling number translation pattern I set the calling line ID presentation to Restricted and it correctly shows Private on phones but the voicemail shows the dummy calling number. The CUCM logs show that it is sending the calling number to CUCX.

The dummy number translations on the gateway are a bit convoluted to me so if there is a better way to do this, please let me know.

This is CUCM and CUCX 8.6 with a SCCP integration.

Thanks,
Eric
