[asterisk-users] How to set up Fax on Asterisk - Using analog Fax machines and HT502 (or FXS of a Digium TDM410P)

[hin lee]

Can't upgrade the version..... how about buying a FXS gateway and be done with the issue.  Go to ebay and search for AudioCodes.  You can get 1 FXS port gateway for around $30 to 2 FXS at $85.  Probably the best bet is to convince the customer to upgrade Asterisk.

Hello Asterisk users,

We are having MANY but MANY problems configuring an analog fax machine to work properly on Asterisk, the first thing we do was to plug in the Fax analog machine to the FXS port of the Digium TDM410P, we set echocancel=no on zapata.conf and also faxdetect=yes on general section, but our Asterisk CRASH every time we try to send/receive fax!

We are using Asterisk 1.4.21 and Zaptel 1.4.11; the card does not shows any interrupt in /proc/interrupts

We also tried with a Sangoma B600 on this machine and the same result! Then we tried with the sangoma and digium card on another asterisk box, with Asterisk 1.4.30 and DAHDI 2.2.x and the fax was not reliable 100% but at least Asterisk vener went down

We cant make any upgrade of Asterisk/Zaptel due to some rules of the customer, the do not want to use fax2email, they need to use the panasonic fax machine, this is driving me crazy!

We also tried with a HT502 with passtrough fax mode and pcmu and pcma enabled and the same result, asterisk does down when trying to receive/send a fax

What could solve our problem? what else should we try about configuration? just faxdetect=incoming and set echocancel=yes and that's all? Please your help, we really need to put this working

Thanks in advance for all your help!
