We are trying to get faxes through out voip lines. But still not succeed. We have a commercial version so that shouldn't be the problem. Faxes received through our patton gateway (isdn lines) are working smoothly. But we also want to have the voip lines being able to receive faxes. The did for the test line is all calls are fax calls and the fax is send to the extensions which is also used for the isdn faxes. What am i missing here?
