When I am calling a PBX with recognize the FAX and route the call to the analog fax I have two issue.
1) The PBX is not able to recognized the FAX, therefore, someone transfers the call manually. I reduce the wait from the example and also removed it without any luck
2) When the transfer is done, 50% of the time the FFA fails
Is there some setting that I am supposed to adjust to increment the timeout or this "handshaking"
