scope:

This Recommendation contains the framework of session initiation protocol (SIP) signalling test requirements between SIP-enabled devices for real-time fax over IP (FoIP).

Three methods for the support of fax over IP have been identified:

1) Pseudo-VBDoIP emulation;

2) FoIP packet relay with [ITU-T T.38]:

- [ITU-T T.38], Annex D for call control signalling (SIP/session description protocol (SDP));

- [ITU-T T.38], Annex E for gateway control signalling [ITU-T H.248];

3) VBDoIP pass-through method as defined in [ITU-T V.152].

Where there are discrepancies among this Recommendation, [ITU-T T.38], [ITU-T V.151], [ITU-T V.152] and [ITU-T V.153], these other Recommendations take precedence over the text and procedures referred to by this Recommendation.
