similar to: Blank page when sending faxes (repost)

Guys, I have been a trying to send a fax using spandsp/app_rtxfax/asterisk. I'm trying to send a (3 page) fax, and all I'm receiving is a single blank page (and I've tried it with 2 fax machines). As some background, I'm using asterisk with an E1 connection through a Sangoma WAN card -- all of this has been working with voice for over 6 months. The software is all working too

Hi, I am trying to recice a fax with * using SpanDSP - but it doesn't create the output file. (See the bottom of log file). * Loads both app_rxfax.so and app_txfax.so fine. Also I can't make * autodetect an incomming fax call (yes I have enabled faxdetect=both in zapata.conf - though it's not a Zap device) Any ideas are welcome :-) Best Regards Michael L?jtnant System Details:

Hi, I have tried to install and configure the FAX app using the steps described in several mails on this list. When a FAX call arrives on X100P, the fax extension is executed, which looks like: exten => fax,1,RxFax(/var/spool/asterisk/incoming/${CALLERIDNUM}.tif) exten => fax,2,Hangup It tries to negociate, but nothing is received at the end and the other part times out. More, after this

Hello, I tryed out spandsp with libtiff-3.5.7 and with Asterisk from CVS. I tryed to receive a fax on a CAPI channel. Finally I got a file with 8 byte length (/tmp/testfax.tif). How can I do next?

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

Hello, I have spandsp working with asterisk (tested on one PSTN fax machine). Today someone wanted to send me a fax, but there was a problem with the TIFF file. This is what asterisk console says: TIFFReadDirectory: /var/spool/asterisk/fax/1140608321.7.tif: cannot handle zero number of strips. MissingRequired: /var/spool/asterisk/fax/1140608321.7.tif: TIFF directory is missing required

I've been using spandsp and rxfax to receive faxes for a while now and over the past few days I've looked into the other side of things - txfax. I can't seem to get it working properly. I've included debug logs below of both the tx and rx side of things. I've tried three different servers, asterisk v1.0.6, 1.0.9 and CVS, FC2 and FC4, libtiff 3.5.7 and 3.7.1, TE405P and

Hi, so far I had our PRI line connected via Digium TE410P and ZAP channel to asterisk which worked perfectly. I now have a second line coming in through a H.323 gateway and chan_oh323. rxfax() still works and receives faxes with G.711 alaw codec, but I always get one empty first page via H.323 - a one-page-fax becomes a two-page-fax with one empty page in front of it. It seems the empty page

Hi all, Trying to get fax reception going using a voicetronix openline4 card, however, there are two issues (as far as I can see) (1) Currently the voicetronix world (cards, firmware, drivers, channel prog etc.) does not do fax tone detection. I have spoken to the voicetronix guys , understand what has to happen there and may do some hacking if I can resolve the second issue. Meanwhile, I

hi, it seems that spandsp-0.0.2pre22 is not functioning right. downgrading to pre21 makes it work again. debug messages: Jan 18 11:54:29 DEBUG[5157] app_rxfax.c: FLOW Changed from phase 1 to 4 Jan 18 11:54:29 DEBUG[5157] app_rxfax.c: FLOW ???: Jan 18 11:54:29 DEBUG[5157] app_rxfax.c: FLOW Real-time Internet fax (T.38) Jan 18 11:54:29 DEBUG[5157] app_rxfax.c: FLOW V.8 capable Jan 18 11:54:29

I've seen people mention that they have fax reception working with Asterisk, spandsp, and app_rxfax. I'm using the latest Asterisk from CVS, SpanDSP 0.0.1k, and the latest app_rxfax.c (as mirrored by friendly list members recently), and libtiff 3.5.7. Asterisk is detecting the fax signal properly, and executing the fax extension in the dialplan. The fax part of the dialplan is pretty

I am having a problem with SpanDSP. What happens is when I send a fax to SpanDSP the fax message seems to fail in the training phase. I think it's a timing error, however I have no idea about how to rectify the problem. I have included a copy of the log below. I am using a Digium TDM-400P card with 2 x FXO ports and 2 x FXS ports. The fax is connected to one of the FXS ports (Zap3). The
