Does anyone know of a device you can install between a fax machine and an "analog" VoIP line or Ethernet port that will increase the reliability of faxes. The VoIP network we are connected to does NOT act as a T 38 gateway so this issue is getting very tough to solve. I have tried finding a stand alone device (that does not require using a service) that will capture a fax and then convert it into a reliable analog stream for legacy fax machines, but I have had no luck in finding one. Please help!
