problems receiving faxes over PRIs with spandsp. I currently have 4
systems, 4 PRIs from 4 different providers... none of them get better than 50%
success rates receiving faxes in spandsp, I constantly get cut off pages.
No body seems to have a fix for it, and it is really frustrating.
Supposedly it is caused by "frame slips" on the PRI, but if that is
the case, I am 4 for 4 getting crappy PRIs that can't keep time. <br>
<br>
These same boxes work fine when receiving faxes over fxo ports, or if I plug a
fax machine into an fxs port and call in to a spandsp extension the fax will be
received just fine, so I am left thinking it must be the PRIs, but if all PRIs
are this bad, how can anybody be using them? <br>

We also route via a PRI to our other phone system to hylafax on an<br>

<br>
Hmmm, Im not so sure I can apply this to me though. I just want to
do<br>
Fax-To-Email using PRI channels as the incoming lines. Not so much<br>
transfer<br>
to a real fax. <br>
<br>
I am assuming that this is easily done with Asterisk? (I did it before<br>
with<br>
Asterisk SIP, but it only worked once every 10 tries or so)<br>

I'm having good success doing fax over PRI using a TE405; one span to<br>
the<br>
PRI, the other to an FXS channel bank that is almost obscenely <br>
underutilized<br>
(3 channels).<br>
<br>
I also have channel bank - T100P - IAX2 - TE405 - PRI, where the IAX2<br>
link<br>
is a 1-hop SDSL (VOIP only) data link. This works well too.<br>
