Hi Cyril,
Good work. process_baud is a fairly big routine, and your backtrace
doesn't give the actual line number at which things fall over. However,
studying the code I see that I do not protect against the possibility of

The issue in this thread is the frame transfer rate for the TDM analog
card almost always exceeds the 1.000 seconds expected by the design.

Why would you expect a bunch of fax modems to work any better than
spandsp? If spandsp doesn't work reliably your system is very likely broken.

Hi Steve,
I sent a mail to this list a week ago regarding exactly this issue.
Spandsp doesn't work for me (getting 200rows tiffs), but sending and

problems.

Hi Andrew,
If you can catch one of these events, and get a traceback of the stack,
I will take a look. This is not happening to most users, so it must be
some specific combination of things on your machine. I have reports of
high volume faxing running for extended periods from some users.
Hi Julian,
Sounds like a frame slip problem if the result depends on the source.
Most people, including me, have trouble with the TDM cards. They worked
without problem when I was first developing the FAX software in spandsp,
so I assume the TDM driver has gathered bugs since that time.
As Steve has mentioned several times, it seems the TDM-fxo boards
have an issue with missed frames that no one is addressing. Very few
(if any) TDM users have been able to make spandsp function correctly,
and the few that might have it working don't know why.

Nope; it's not a tiff issue;

I'm trying to see if anyone knows of an alternative solution, commercial

It's not that SpanDSP ties up extensions, as it definitely doesn't. I
