Lets follow the industry standard here: Yes, we support T.38.
Actually we don't right now. It is still in development. However I have
recently experienced many bits of VoIP kit that say T.38 on the box,
while having no T.38 functionality at all. Clearly claiming T.38 support
when you have none is the industry standard. :-) This is more than just
a whimsical comment. A lot of people think T.38 will be a magic cure for
FAX. It you look at
- the number of boxes which don't claim to support it;
- which do claim to support it, but don't;
- which support it, but in a very buggy way;
- which really work
you will find the last group is the smallest.
Another issue is "what are you trying to do?". People vaguely say "do
you support T.38" when there are several ways in which it might be used.
Within openpbx there are basically three forms of T.38 support being
implemented.
- T.38 pass-through of UDPTL is nearly ready. Passthrough of SIP and
TPKT is in progress, but most boxes that do T.38 only support UDPTL anyway.
- T.38 termination (which really means termination or origination)
to rxfax and txfax is in testing. T.38 termination to chan_fax will
probably be added at some point.
- T.38 gateway, between traditional telephony kit (PSTN lines, fax
machines plugged into FXS ports, etc) and the IP world, is in testing as
a standalone module. It still needs to be integrated into openpbx.
