[asterisk-users] Asterisk - Spandsp Fax not working?
Hi all, I'm trying to setup an asterisk based fax receiving machine. i'm using asterisk 1.2.18 and app_rxfax with spandsp 0.0.4pre9 I have no problems with a modem-fax, but with the fax machines i have tried almost every fax fails, both in sending and receive. the machines are sending a receiving a lot of faxes every day and working well, so i think the problem is on the spandsp side. i have tried almost every spandsp version from 0.0.2 to the current one, both with and without ECM, but without luck. has anybody succeeded in receiving faxes with asterisk app_rxfax and spandsp? I'm noticicing a lot of different behaviours: sending w ECM gave me an OK, and the second half of the page was missing, other faxes fail with Sep 26 17:26:18 DEBUG[4741] app_rxfax.c: =============================================================================Sep 26 17:26:18 DEBUG[4741] app_rxfax.c: Fax receive not successful - result (11) Unexpected message received. Sep 26 17:26:18 DEBUG[4741] app_rxfax.c: ============================================================================= can anybody help me? thank you in advance, marco -------------- next part -------------- An HTML attachment was scrubbed...

I am using 0.0.3 on centos 4.5, asterisk 1.2.24 and freepbx 2.3 and it is working very well. One very important thing to keep in mind is that faxing over voip will only work reliably with ulaw or alaw and your internet connection MUST be able to sustain a constant data stream with low jitter. If your interested I have a shell script to install asterisk 1.2.24 and freepbx-2.3 with rxfax and txfax on centos 4 and working on centos 5.
