similar to: Sending many faxes simultaneously with spandsp

Per: http://soft-switch.org/spandsp_faq/ar01s07.html FAXing with spandsp keeps giving me core dumps. Its crap, isn't it? Actually the crap in this case is probably libtiff. Versions 3.5.7 and 3.6.0 seem reliable. The FAX image handling in version 3.6.1 is broken. All the core dump problems I have investigated turned out to be due to a very old version of libtiff, or version 3.6.1. I am

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

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

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

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

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

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, People often send me audio logs from spandsp's soft-fax machine, where they have problems with corruption in the middle of a page for most or all of their faxes. Their problems are usually due to frame slips. However, recently I have received audio logs from two people who generally have great success with my software, but who find one or two machine regularly fail to send faxes

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 =>

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

-----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)?

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

I've a stock RH9 system with spandsp 0.18. Faxing out over a PRI to a USRobotics modem on a stock Suse9.3 system with hylafax fails with the following errors in the hylafax logs: Jun 30 19:28:53.23: [ 608]: RECV/CQ: Bad 1D pixel count, row 0, got 595, expected 1728 Jun 30 19:28:53.23: [ 608]: RECV/CQ: Bad 1D pixel count, row 1, got 595, expected 1728 Jun 30 19:28:53.23: [ 608]: RECV/CQ:

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 tried to use txfax to send several faxes at the same time. It seams, that one can't send more than 3 faxes at once, or one risks to get 50% and more aborted faxes due to errors. The CPU usage is below 97%. I tried with Opteron and IntelP4: same result. Ok, I know, that faxing via a digital line is complicate, and I shouldn't complain, but I would like to know, whether these are

OK I see the ponit (although I never said that second page is interrupted - I said that in some combinations of resolutions and TIFF options receiving fax "spits" another blank sheet of paper beside the clearly received first page). I have read someware (some faxing tutuorial) that there is some kind of control code (6 EOLs I belive) that should be in TIFFs between pages and that

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

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

Nobody seems to use txfax or does nobody have any problems with it? I have sent mails to most lists and get no reply. I cannot get a fax to go through with txfax. I use a call file as a test and all I get on the receiving fax is a bunch of vertical lines. my call file is: Channel:Srx/gout/4658158 MaxRetries: 0 WaitTime: 20 Application:txfax Data:/etc/asterisk/testfax.tif|caller|debug FYI
