I'm trying to put a Fax solution together. What I have is a 2821 Voice Gateway (MGCP) that contains the FAX DDI. I'd like to set this DDI as a CTI_Route Point that then forwards all calls to a group of 4 ports configured on the VG224 (also MGCP). These ports are connected to a Fax Server.
The problem I have is that when the call reaches the Fax Server - the original dialled number is not coming through so the Fax Server doesn't know who the Fax is for. I've looked at various service parameters and settings but can't seem to get this working.
Any help greatly appreciated.
