seems to not be possible to get the Header from
The list of options available are listed here

Hello,
now i added
directmedia=no
disallow=all
allow=ulaw
allow=alaw
and i changed the caninvite part to canreinvite.
Now the faxdetection is working well. But now, after the faxsession has
started, i'm getting
res_rtp_asterisk.c:3548 ast_rtp_read: RTP Read too short
as error.
Regards
in the sip.conf i specified
[general]
sendrpid=rpid
trustrpid=yes
language=de
videosupport=yes
callevents=yes
caninvite=yes
There is a typo in the last line above. Should be canreinvite. AFAIK it's
obsoleted in favor of directmedia. BTW, try to set it to NO.
BTW, what is the codec order?
It is really more interesting the receiving part. Can you paste here?

txfax can insert a header on each page when it sends a fax. There is a
parameter for that.
When a fax is received the header you see is part of the image. As
Steve, the stuff below was in direct response to a user question
regarding T1 timing sync and understanding why that might be
important relative to spandsp and/or other modem use. So it does
apply directly. (Of coarse it slid into a tangent.)
It doesn't help at all,

the crystan and the derived clock is usually tunable.
Nope. Its always a crystal. Its either a

Mr. Rubinstein:
I have read a lot about the thread of faxing support in Asterisk as
well as spanDSP. However, either I don't fully understand other
people's applications or may be what I'm trying to do is different
from what others are trying to do.

It doesn't make any difference. The pcm data that arrives from the telco
is buffered in the zaptel and/or asterisk code, and sent out the second
T1 card as soon as it can. That buffering reduces (or eliminates) the
need to sync one T1 card to another.
Actually.. I
seem to have jumped to improper conclusion..
One thing you will
find abour spandsp is that some fax machines will just plain have a problem
sending to spandsp, period. Mr. Underwood has localized it to cetain HP fax
machines and I can confirm that HP all-in-one
