Re: [Asterisk-Users] T100P frame slips
Michael Welter wrote: I posted last week that taking timing from either the T100P or the Adtran TA750 had no effect--that my fax transmissions crashed either way. It turns out that the T100P card is bad and delivers random slips during a fax transmission--sometimes after several pages printed. Replacing the card solved the problem. BTW, the slip is not audible on a butt set. What a waste of time. This point is interesting. On most systems, if you cannot here regular ticks its pretty certain there are no slips. With the Digium cards, for some reason, many people have slips (usually due to configuration issues rather than faulty cards) yet were unaware of this until they have trouble with my spandsp software.

That is weird. I am receiving faxes with no issues at all now using spandsp and app_rxfax, however passing the same audio stream on to a real fax machine (Canon IR3300 and/or some manner of ancient laser fax which does support > 9600 baud) causes bad receives. This is on a TDM430P, and was tested in a Xeon 2.8 Supermicro motherboard and also on a rinky-dink old P3-800 (app_rxfax works just great on the latter and is in fact what we're using). Want to know the kicker? sending faxes out from either of those fax machines mentioned above through the exact same TDM430P... no issues at all. Just receiving. A T100P + Adit600 channel bank had no problems with those same faxes with the same SuperMicro server. -A. ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

Try commenting out ;echocancel=yes ;echotraining=yes I bet your faxs start working in both directions. But of course you will now have occasional echo problems.

I read somewhere that to be able to hear the fax tones you need to give Asterisk 1 or 2 seconds to be able to pick them up. So put a Wait(1) or Wait(2) in your dialplan (directly after Answer would make sense to me) so Asterisk can figure out it's a fax call and throw it to the fax extension. Merry Xmas!

While this is true, it doesn't apply to my particular case -- I have a DID specific to faxes which is thrown to my "faxsterisk" box over IAX. Basically PRI -> colo* < dedicated IAX2 link > faxsterisk -> TDM430P -> faxmachines faxmachines -> world = good faxes world -> faxmachines = 50+% failure rate world -> rx_fax on faxsterisk = good faxes -A. ___ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
