Current version of sipXtapi does not support faxing, only voice and (somehow) messaging are supported. > B.

You may look on SpanDSP for open-source realization of T.38. To bind it to sipXtapi you have to create new MpAudioResource child class, embed it to MpRtpInputAudioConnection and create notifications to report detected data to sipXtapi level. Instead of creating new audio resource you may modify MpDecode - it would be simpler on first stage, but harder to maintain, I think. -- Regards, Alexander Chemeris. SIPez LLC.
