Forwarded Calling Number Presentation

Unanswered Question

Hi,


My VoIP topology is as follows:

CUCM6.1 talks to 2 gateways: one for outgoing landline calls, one for outgoing cell phone calls. Incoming calls all use the landline gateway.

My problem is in caller number presentation when incoming calls from landline gateway are forwarded out of cell phone gateway. How can I send the orginal caller ID instead of the forwarding phone id to the cell phone gateway? For example, phone A calls from PSTN into landline gateway, and to a CUCM phone B. Phone B forwards all calls to cellphone C. I want phone A number is presented on phone C as the calling number. The cell phone service provider agrees to present any calling number I send to them.

How can I achieve this?


Many thanks in advance.

Hi,


In the H323 gateway configuration page, under 'Call Routing Information - Outbound Calls' select 'originator' for 'Calling Party Selection'.


Cheers.
