T.37

T.37 is an ITU standard for sending FAX across IP networks in a store and forward mode.
FAX messages are sent as MIME encoded email messages using SMTP.
There are equivalent IETF RFCs.

Venta4Net Plus, a Windows GUI application that includes email2fax gateway capability and supports both T.37 and POP3-to-fax methods. It can also act as an email2voice gate (dials a number and plays a pre-recorded emailed WAV file). Works both over PSTN through fax modems and over SIP/H.323 VoIP telephony (T.38 is supported).
