[Asterisk-Dev] Re: Fax and h323

[Steve Underwood]

I can confirm that any faxing over IP is hit and miss unless it uses 
T.38, and even then most implementations of that are buggy. Since both 
SIP and H.323 use RTP as the audio transport medium, the results should 
be precisely the same whichever you use. If not, you probably did 
something wrong.

TRANSPORTS HAVE NOTHING TO DO WITH SPANDSP.

I hate to shout, but people really do find it hard to get to grips with 
that.

Regards,
Steve
