similar to: SpanDSP not sending to fax extension.

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

Hello ! I 'm trying T.38 faxig with spandsp using rxfax/txfax as fax terminal. As another endpoint I 'm using Grandstream HT 486 ATA and a fax machine. Has anybody success with the HT486 as T.38 terminal ? ATA as originator: I managed only onetimes a successfull T.38 fax session. The other times the HT486 did not initiate a re-invite with T.38 parameters. Or shall the Terminator

Hi everyone ! I have some aditional info on problem with TXFax and sending multi-page TIFFs. I have made 6 different multi-page TIFFs (Group3 1D with fillbits EOL aligned - 3 pages one TIFF in lowres and one in hires, Group3 2D -3 pages againg in both resolutions , and Group 4 - 3pages in both resolutions), and then tried to send them to Panasonic KX-F1100, Panasonic KX-F500 and SpanDSP

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

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

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi all, anyone else seen RX/TXFax crashing Asterisk on latest Asterisk SVN? I've now seen it on two machines I tried to set up - one it seems because the tiff file was malformed, but the other is doing: tiff -> tx fax -> zaptel -> pstn -> ddi -> zaptel -> rx fax -> tiff The above crashes every time. If no one else has

It seems that Spandsp has everything in it (when you include rxfax and txfax) to be a T.38 termination when used with Asterisk 1.4? And if so, what version of Spandsp? What version of IAXModem (so I don't have to also deal with T38Modem)?

Everyone, Just thought I would drop a line telling everyone here I have the software RxFAX/TxFAX up and running without any real problems. I did have to..... RH 9.0 1) Install an audio devel rpm 1) install libtiff from source, and copy over a bunch of include files to /usr/local/include 2) build/install spandsp 3) move app_rxfax.c and app_txfax.c to apps/ dir in asterisk source tree. 4)

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

Hi Steve and all, 1. Faxing from asterisk back to the same asterisk (from one Zap channel to another) doesn't work for us. Txfax called with the 'caller' parameter issues CED, while the receiving side needs CNG in order to switch to fax extension with rxfax. 2. This is probably the reason why J2 and our UC don't recognize incoming fax. Thank you. Alex Zarubin Webley Systems

Hi, I noticed a strange behaviour: Faxing using spandsp (TxFax) from my asterisk box to my old, common fax machine at home works fine. Faxing from the same box to my office pc-fax (Hylafax) also worke fine. Receveiving faxes on my asterisk box using spandsp (RxFax) also works fine. It is a PSTN number connected to the digium card of that asterisk box. Then I faxed from my asterisk box (TxFax)

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

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.

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 =>

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 have installed the latest version of asterisk(1.4.0-beta3), and built app_rxfax/txfax. I'm using spandsp from here, http://www.soft-switch.org/downloads/snapshots/spandsp/spandsp-20061207.tar.gz Everything builds ok. I had to manually apply the patch from the site so configure would spot spandsp libraries. However, when I try dialing my virtual fax extension (either from a phone or

Thanks for the information Lee ! Still, something is still strange to me, since this two Panasonic Fax machines are receiving at least 20 multi-paged faxes a day (they are in same office as both Asterisk boxes, and me :) ). Beside that, POTS lines in those two faxes are from same PSTN switch as line in X100P in one of Asterisk boxes, and the ISDN PRI lines in other Asterisk box is from same PSTN

1. What is the difference between Asterisk v1.6 RXfax/TXfax and Digium Fax for Asterisk? 2. Is Free Fax for Asterisk identical to Fax for Asterisk nonwithstanding the 1 channel limitation? 3. Can any purchase of Fax for Asterisk count as channel 2+, when used in conjunction with Free Fax for Asterisk? 4. When (If ever) is colour support likely? Michael

Hi, all. I'm getting a lot of [Feb 3 13:56:36] WARNING[3721] /usr/src/asterisk/spandsp/agx-ast-addons/app_rxfax.c: Channel T30 DONE < 0. in my log file, and incomplete fax reception. Any idea what might be going on? I've googled a fair bit, but haven't seen anything leap out at me. Thanks, -Ken
