When feature F-1450 is configured, using the same dialing number, the IMG will be able to switch the SIP call from a voice endpoint to a fax endpoint device. A SIP user first dials a number and the call comes into the IMG. The IMG then routes the call through an outgoing channel group to a configured voice endpoint such as a SIP voice gateway. Within this call, the user then sends a fax and the IMG detects the fax tone. The IMG then disconnects the outgoing side of the call from the initial voice external gateway and reconnects it to the fax external gateway. The call is now connected to the fax device, and the fax is thus sent to the proper destination. Because the call is always routed to a voice endpoint, the call remains at the voice endpoint if no fax tones are detected. The call doesn’t switch to the fax endpoint. For more information see below.
