the attached log with verbose=6 and debug=6 refers. we've got a sangoma A104 (no hwec) with PRI ports 1 & 3 loopbacked to each other. we're trying to have txfax send out on one of those pri ports with rxfax listening on the other side, hence having asterisk send a fax to itself. we however have bad, and i mean really bad (<10%) success rates. we're currently using asterisk 1.2.24 with spandsp 0.0.4-20071214 (snapshot of 14/12/07) and we keep getting "Fax send not successful - result (25) No response after sending a page." errors. ECM is turned on in both app_txfax.c and app_rxfax.c. from what we gather just reading the code, time T4 expires in txfax because apparently rxfax is not sending a response back out, and thus after the maximum message retries (3) txfax just drops the call, leading rxfax to say that the call was dropped prematurely. does anyone know what's going on here, and if there is a version of spandsp which could work in this scenario ? -- Regards, /\_/\ "All dogs go to heaven." dinesh at alphaque.com (0 0) http://www.openmalaysiablog.com/ +==========================----oOO--(_)--OOo----==========================+ | for a in past present future; do | | for b in clients employers associates relatives neighbours pets; do | | echo "The opinions here in no way reflect the opinions of my $a $b." | | done; done | +=========================================================================+ -------------- next part -------------- An embedded and charset-unspecified text was scrubbed...

It sounds like there are dropped packets or something. dave
