I am using a digium TE110P and a TDM04b (or whatever the one with 4 FXS ports is called) on a Dell PowerEdge 2850. No problems at all with faxing with a cheap fax machine, though the asterisk box almost never goes above 5% CPU usage unless there are some conference calls going on. I can run modems/faxes just fine (though the modem connections seem to have a bit more latency than through a POTS line, it is acceptable for our use.)
Just be sure to set echocancelwhenbridged=no and tweak your txgain and rxgain on the line (this is not a do it once and you're done thing, I had to go back probably 5 times over the course of 2 weeks to get the right numbers.) I am even doing a redirect to eFax (I'd do with asterisk but we already had an efax account and it works well enough) on one of my DIDs and it works great. Quite honestly I found a lot of documentation on how faxing in Asterisk is hard, and I just never saw that. Maybe I got lucky with a magic combination of hardware and forgiving fax machine, but it kind of just worked the first time I tried it. Now, if only setting up a 'page all' function on Cisco 79XX SIP phones without using a line appearance was so easy... -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Rich Adamson Sent: Friday, April 14, 2006 8:37 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] Digium cards, so disappointing !

Running zttest on my box with both a TDM04b and A200D installed indicates and average of 99.96% for both. Not sure how accurate that might be as the A200D card appears as a 24 channel interface in terms of /dev/zap even though only four ports are equipped. The TDM04b won't support faxes on this box under any circumstances and I've played around with about every possible pci latency, etc, change that folks have suggested in the last two years. Based on my heavily invested testing to date (which includes about two years of doing this), the "only" usable fax support thus far comes from using the A200D card with the fax machine directly connected to a fxs port on that card, and an fxo (pstn) port on the exact same card. Those fax tests have been 100% solid using a cheap/older Brother fax machine. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
