Well, there are 2 issues to this. The first is the gateway that receives the call from E1, can it make the distinction between the 2 and reroute based on that (doubtful) and I know Quintum cannot do this, but the 2nd point is the one that matters, when the call comes in from E1 it is not noted as fax or voice. You never know if it is a fax call or voice call till it connects to the other end and the gateway hears the fax tones.
