Hi Last month, people reported a crash with Asterisk 1.2.13 and spandsp-0.0.3 when receiving a fax using fax detection. Today I've tried 1.2.14 with the latest spandsp 0.0.3pre27 and with the snapshots for app_rxfax.c and app_txfax.c. The problem still happens. Has anyone found how to resolve this issue? I tried emailing Steve Underwood (with crash backtrace) but he hasn't

what method is preferred: haylafax and Iaxmodem or spnadsp for faxing. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20071228/e829632a/attachment.htm

Sorry to bore you more with the clock issue, but have you check /proc/zaptel/<span> to make sure it's not missing interrupts? There's also an option to record the audio for the fax, you could listen to that vs a recorded file that will receive correctly on a fax machine and see whether there is an obvious difference? (Good luck, that'll be really scraping the barrel!!) Does it

>Does IAXmodem allows you to receive faxes with any extensions >(auto-detecting incoming faxes). You just let Asterisk do the fax detection for you, and when it hears CNG, send it to the fax extension, and your fax extension would just Dial() one of the IAXmodems (using IAX) >>DRi@b-w-computer.de wrote: >> sure in an small office you can use iaxmodem/hylafax to receive faxes

Hi, I've been trying to get fax going for the last few days. I can receive fax with Spandsp 0.0.2pre19 on Asterisk 1.0.9 with rxfax, but when I tried sending the received fax file to a fax machine, I either get "line error" or just a blank page. Is anyone using Spandsp to send fax to fax machines on PSTN? I've run out of things to try now, and I'd really appreciate if

We are doing this with the latest spandsp, iaxmodem and hylafax. Seems to work very well for us so far. -Jonathan > -----Original Message----- > From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users- > bounces@lists.digium.com] On Behalf Of Michael Gaudette > Sent: Tuesday, March 21, 2006 3:34 PM > To: 'Asterisk Users Mailing List - Non-Commercial

Hi, I'm using spandsp-0.0.3 [http://www.soft-switch.org/downloads/snapshots/spandsp/ spandsp-20061116.tar.gz] on a bristuffed asterisk (1.2.13) [http://212.91.251.199/~junghanns.net/downloads/bristuff-0.3.0- PRE-1v.tar.gz] libtiff is at version 3.6.0 Running on: Linux router2 2.6.17-2-686 #1 SMP Wed Sep 13 16:34:10 UTC 2006 i686 GNU/Linux Debian testing distro.

I want to setup a phone system that can allow the caller to type in a faxback number, and automatically be sent a fax file. Is this possible with Asterisk? Or using Asterisk & a Linux fax program? I've seen stuff about incoming faxes, but nothing about outgoing. This is over a Zap channel, not IP, btw. Thanks.

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

Hi all!....i'm in course to implement Faxing in my asterisk box and for that I've installed all succesfully like libtiff and spandsp and next rebuild and reinstall asterisk modules, but when i call to Rxfax from dialplan nothing happens and i get some errors like "XCN with final frame tag In state 9" or a paper copy of a transmision report from the fax machine with COMMUNICATION

Hi all, I'm trying to setup an asterisk based fax receiving machine. i'm using asterisk 1.2.18 and app_rxfax with spandsp 0.0.4pre9 I have no problems with a modem-fax, but with the fax machines i have tried almost every fax fails, both in sending and receive. the machines are sending a receiving a lot of faxes every day and working well, so i think the problem is on the spandsp side. i

Hi, all. I've got a fax extension in my extensions.conf, but spandsp never sends my faxes there. Both applications -- txfax and rxfax -- are registered by Asterisk, so they compiled and installed correctly. I've got a Sangoma A104 card, and (as some people had suggested) have loaded ztdummy. Everything seems fine, except that it never gets recognized as a fax. I've even turned off

I am getting pounded by junk faxes. I have noticed that all of them have no callerid. Can I set up a dial plan to ignore a fax if no callerid is sent? I am using RxFax (spandsp) on an x100p card. Thanks John Hill

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 =>

Hi all, I have problems with rxfax application. It seems to be ok but I don't receive the fax in my directory. My extension.conf is as follow: [macro-fax] exten => s,1,SetVar(FAXFILE=/var/spool/asterisk/incoming/${UNIQUEID}.tif) exten => s,2,rxfax(${FAXFILE}) [fax] exten => 100,1,macro(fax) [reception] exten =>s,1,Answer() exten =>s,2,Background(00) 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 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

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:

Hi, Having problems with getting either RxFax or FaxReceive to compile. Running Asterisk 1.4 on CentOS 5. Does anyone have the free/open source executables that you could send me? Thanks for your help! P. S.: TxFax and FaxSend would also be appreciated.

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
