We are pleased to announce that we have successfully completed interoperability testing with Fax Voip T38 Fax & Voice software. Fax Voip is a Windows based software that provides a full-featured SIP/H.323 softphone for Voice over IP (VoIP) calling. It also provides full functionality for sending & receiving facsimile transmissions via T.38 & G.711. From the perspective of your fax or voice application, it acts as a Voice/Fax modem, installing Virtual COM Ports and Virtual Fax Voip 14.4k TAPI Voice-Fax modems on your system. You can configure your Fax & Voice program to operate with both the Fax Voip COM ports or virtual modems. From the perspective of your VoIP network, it provides a fully featured SIP/H.323 client with support for faxing over VoIP trunks, both in G.711 and T.38 (and more importantly, with Error Correction Mode - ECM!).

Fax Voip's software passed our rigorous testing requirements and made it to our Certified Device List. We’ve included a simple configuration guide on our website to help you get up and running.
