Hello, I'm trying to receive faxes with asterisk. My configuration is like this: PSTN fax -> ISDN -> Cisco router with VoIP module -> Asterisk When I try to send a fax from PSTN fax I got the standard fax signal, Asterisk starts rxfax application and then call ends and there is no tif anywhere. On the fax display there is still one message: Calling... Part of my extensions.conf:

Dear All, I'm having problem with spandsp/txfax, I'm not able to send a multi paged tiff file, the fax machine receives the first page of the document and complains about communication problem. The file what I'm trying to send has 2 pages and is received & generated by spandsp/rxfax. Searched in the archives, but found no solution. I'm using: Dell Optiplex PC Inoteska Quad

Hi, I am trying to receive a fax with the spandsp library. The sending fax says "success" but there is no tiff file generated. I use "exten => 7000,1,rxfax(/tmp/testfax.tif)" in my extensions.conf. The connection is via SIP/G.711 as I have read on the list that this can sometimes work (I know Fax over IP is troublesome without T.38). I think the transmission should not

Hi all, After a long time having no time, I have finally done some fresh work on my software fax machine. I have replaced the original carrier tracking with something more robust. I have also added 4800, and 2400 bits per second modes, and cleaned up a few bugs in areas like superfine mode operation. I apologise for this update taking so long. At ftp://ftp.opencall.org/pub/spandsp you will

Hi, I have an Asterisk CVS-HEAD-08/29/05-13:21:43 built on a Redhat 9. I have problems to receive faxes with spandsp-0.0.2pre11 and libtiff-3.5.7-11. I'm trying with a fax machine Panasonic KX-FT25, 14.4Kbps modem speed. I have tested sending a Fax document from Asterisk to the fax machine, it is working fine, but when I try to receive with asterisk, I receive transmission error on the fax

Hi all, There is a test version for the next release of spandsp at ftp://ftp.opencall.org/pub/spandsp/spandsp-0.0.2pre2 Only use this if you wish to experiment. In general, using spandsp-0.0.1 is probably more stable right now. If you have had problems with Canon FAX machines not accepting FAXes from spandsp-0.0.1 you might like to try this version. I have had at least one report from

Hi, I'm trying to use the spandsp fax-back facility and despite I can send and receive faxes, this is not working fine. I would like to get a debug of what is going on. I am using the flag debug, but I don't know if txfax is generating any log information or where it is saving it. I just don't find anything. My line in extensions.conf is: exten =>

Hi, Several people have reported problems sending faxes from spandsp-0.0.1k to Canon FAX machines. A spandsp user had the same problem with another make of FAX machine, and traced the problem to a bug in the file t30.c of spandsp. Line 542 says s->t4.rx_file[0] where it should say s->t4.tx_file[0]. This fixes his problem, and I suspect it will also fix the Canon fax machine problem.

I am attempting to get fax detection to work. I am using a NETjet-s card under ISDN4Linux. Asterisk does not seem to be detecting the fax tone. I have tried following as a test: [MainMenu] exten => s,1,Answer exten => s,2,DigitTimeout(3) exten => s,3,ResponseTimeout(5) exten => s,4,Background(Welcome) exten => s,5,Background(MainMenu) exten => fax,1,Dial(Zap/1,,d) [FaxTest]

I have managed to get spandsp working, and if I dial a specific extension I can receive faxes. WhooHoo. However, I was wanting to use the "fax detect" option in order to allow individuals to receive faxes, but can't get that to work. Given the following extensions (mainly copied from examples on the wiki), why is the call simply passed onto the sip device rather than being

Hi, I'm trying to setup a system where incoming faxes are received using SpanDSP and then send on to another (remote) fax machine. The SpanDSP part is working excellently, however I dont seem to be able to get the forwarding part to work. Heres what I put into my extensions.conf: exten => s,4,Answer() exten => s,5,Set(FAXFILE=/tmp/fax-${UNIQUEID}.tif) exten =>

Hey All, I am attempting to get the RXFax app working and having a hell of a time of it. I am hoping that some of you fine folks can help me out. I have installed Asterisk v1.2.14, SpanDSP v0.0.2pre26 and app_rxfax. All compiled and installed fine. When I attempt to call the extension I have created for receiving fax's then I get the following error once just as the rxfax

Has anyone made spandsp to work with a digium tdm fxo card? I finally got the rxfax and txfax modules to compile, the spandsp lib installed (and in the libpath), and now receive: -- Starting simple switch on 'Zap/1-1' -- Executing RxFAX("Zap/1-1", "/var/fax.tif") in new stack -- Hungup 'Zap/1-1' I've tried to adjust rxgain/txgain in

Hi, I have got my Asterisk server running with TDM400 card (2xFXO & 2xFXS). I originally had the system configured with a Panasonic fax machine on one of the extensions. Due to the high volume of fax spam, I figured it would be a much better idea to capture the faxes as TIF or PDF files to minimize wasted paper, etc. I have downloaded, compiled and installed spandsp and can see the rxfax

I've recently started playing with the RxFax application on my Asterisk box. I've had success, mostly, but I've had some failures, too... The most recent failure is specific to receiving from a particular fax machine -- a "Canon Laser Class 9000S". The TIF images received are readable, but the aspect ratio is stretched horizonatlly (or squished vertically). Is this a

Here's one last plea for help from the list before I give up on the totally cool software FAX modem concept in complete despair (for now, at least, until I have more time to dig into it).... I am simply not able to successfully receive a FAX no matter what device I transmit from or how I bring the call into Asterisk. My lastest effort was a call from a Pitney-Bowes FAX machine into an X100P

I'm using Slackware 11. I unistalled the package that provides libtiff 3.8..... and installed the most current 3.7.... for lib tiff. I downloaded asterisk 1.4 beta3 and the 1.4 beta2 addons and untared them. created a simlink: ln -s asterisk-1.4.0-beta3 asterisk I've compiled spandsp from as follows cd /usr/src wget

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
