T.38 Fax Support

T.38 is an International Telecommunication Union (ITU) standard for the transmission of fax documents over IP networks. T.38 offers reliable VoIP fax transmission because it is more resistant to packet loss than uncompressed faxing over G.711. Furthermore, T.38 Fax generally uses less bandwidth and increasingly is supported as an industry standard.
