Dialogic Brooktrout SR140 fax software is a host-based Fax over IP (FoIP) engine that brings the power of the industry-leading Dialogic Brooktrout fax hardware products to software-based solutions. The Dialogic SR140 is one of the most mature, most widely deployed T.38 implementations in the world, having been embedded into a wide variety of fax server products such as OpenText RightFax, Biscom FAXCOM, GFI Faxmaker, HylaFAX Enterprise and many others.

We are pleased to report that T38Fax.com has passed Dialogic's rigorous FoIP Interoperability testing process, and now appears on their list of recommended SIP Trunks. They have also published a configuration guide that explains the exact configuration they used for testing.
