load). However, I am having troubles faxing through a Linksys PAP2
NA. It doesn't seem to get through at all. Everything else (voice
calls) works just fine. I am using Asterisk Business Edition (
ABE-A.1). I have faxdetect=both in zapata.conf, and I wonder if there's
anything else I'm missing. I know I won't get 100% with fax over IP, but
the success rate for fax on my Asterisk box is just way too low (about 5%, I
would say). <o:p></o:p></span></font></p>

<br>
Wow, strong words!<br>
<br>
Since our experiences with asterisk are mainly positive, <br>
we won't forget faxing through asterisk.<br>
<br>
As long as asterisk is just used as pbx or switch, it is<br>
obviously capable of transporting 100 and more faxes<br>
simultaniously without problems.<br>
<br>
The only thing missing seems to be a reliable modulator/ <br>
demodulator and T.30 machine.<br>
<br>
rxfax/txfax+spandsp is still far away from being reliable under<br>
high load, but developing. Our experience is, that it does<br>
a very good job when sending or receiving single faxes. <br>
As soon as three or more faxes are processed at once,<br>
problems do occour.<br>
<br>
We are currently testing a commercial fax library with the goal,<br>
to implement an IAX client as fax server, in order the send or<br>
receive some dozen faxes simultaniously. It is too early to<br>
say, if we'll succeed, but we hope so, and thus won't forget<br>
faxing through asterisk.<br>
<br>
This is _no_ announcement of a product, since we currently<br>
won't have the right to distribute the library, but we think,<br>
it would be very interesting to know, whether it works or not.<br>
Those, looking for a GNU licenced tool will have to wait for<br>
progresses of spandsp anyway. <br>
<br>
<br>
By the way, the producer of the library announces T.38 support in<br>
some weeks. asterisk just started to support T.38 pass through,<br>
and probably will do it reliably in some weeks. Maybe this will<br>
enable T.38 support for asterisk - though unfortunately not for free nor<br>
open source.<br>
<br>
