Guys. Ive been testing how to receive faxes using TDM400P cards and so far, after playing with gains, echocancell and echotraining on zapata.conf.. Ive ha dno luck, faxes come in as garbage or broken or with blank lines. Anybody has successfully done this? Any tips.. Also I have some ideas: 1. Is it really possible to get fxes on a fax machine using ATAs like the sipura 2002? Even using ulaw and pass-thru, is it possible? 2. Since the faxes is coming from PSTN thru the card, I guess asterisk will always stay in the middle right? No way around this. 3. Im also trying to receive faxes usign a TE110P card with spandsp, unicall and E1 R2MFC, no luck also, some stuff, garbage and broken faxes. Anybody done this sucessfuly? Hope anybody can share their thoughts and insight on this.

The issue has been discussed many times over the last two years or so. There are no known workarounds. Its my understanding that lots of folks have spandsp working via T1 and/or PRI interfaces. The issues associated with the TDM400 card do not apply to the T1 cards.
Hi! I am using tdm400 cards for receiving faxes. It worked quite out of the box. I installed spandsp for the rxfax application only. I use it as phone/fax switch: All incoming calls are answered automatically to listen whether its a fax or not. If it is a fax, the call is forwarded to the buil-in fax extension, otherwise the analog phones (all on tdm400) rings. It works without problems. Its for a small company (about a few faxes per hour) Tom Am Freitag, 24.

I wrestled with this for a long time, as have many others and it just doesn't work with spandsp and asterisk alone. Use iaxmodem and hylafax in conjunction with asterisk... it works like a champ. I have a single POTS line coming in so I get voice & fax with a single number using fax detect. http://iaxmodem.sourceforge.net/ -----Original Message----- From: Rich Adamson [mailto:radamson@routers.com] Sent: Friday, February 24, 2006 7:28 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] fax receive using TDM400P> Ive been testing how to receive faxes using TDM400P cards and so far,after> playing with gains, echocancell and echotraining on zapata.conf..

Any modification made to zapata as far as echo and gains? Should echocancel be on or off? |-----Original Message----- |From: asterisk-users-bounces@lists.digium.com |[mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of |Thomas Artner |Sent: Friday, February 24, 2006 8:25 AM |To: Asterisk Users Mailing List - Non-Commercial Discussion |Subject: Re: [Asterisk-Users] fax receive using TDM400P | |Hi! | |I am using tdm400 cards for receiving faxes.
