Hi, I just sent this to Steve Underwood, but then found a bunch of posts on the mailing list about similar issues.. does anyone have the fix? I'm running asterisk CVS-HEAD-06/28/04-18:13:13, spandsp 0.0.1k, libtif 3.5.7 one thing i just noticed is that calls come in with format '72' which is G711A-law or LinearPCM.. it uses PCM for the call, i assume this is ok the results of RxFAX

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

Rxfax answers, makes handshake, and crashes once the page starts to send. It receives a .tif file of 8 bytes. Asterisk dumps core - gdb shows : #0 0x281fd86c in t4_rx_putbit () from /usr/local/lib/libspandsp.so.0 #1 0x281fea3c in fast_putbit () from /usr/local/lib/libspandsp.so.0 #2 0x28208324 in decode_baud () from /usr/local/lib/libspandsp.so.0 #3 0x2820893f in process_baud () from

Initial handshake sounds fine, but asterisks dies before receive of the fax.

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.

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? Thanks in advance, Thomas ps: what are hardware requirements for sending/receiving faxes? -- creating pipe for PLCI=0x101 msn = 2258589 > sent ALERT_REQ PLCI = 0x101 --

I am also having problems receiving my first fax. I get a 320byte file (for a 4 page fax). If I look a the tiff generated, is just has some few dots. I am sending the fax from a notebook with Windows XP to an X100P and using libtiff v3.5.7. Has anyone successfully received faxes ? Output to the console as follows: Changed from phase 0 to 1 > Start receiving document > Changed from

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

Hi all, I have installed FAX app as described in several mails. When a fax call is received, I get the following in the * console: -- Starting simple switch on 'Zap/1-1' -- Executing Answer("Zap/1-1", "") in new stack -- Executing Ringing("Zap/1-1", "") in new stack -- Executing Wait("Zap/1-1", "2") in new stack

I'm running asterisk CVS HEAD from 20040601 with spandsp 0.0.1k and libtiff 3.6.0 (no other copies are installed). I've put the audio files up at http://www.mixdown.ca/~andrew/dump/akohlsmith-faxsegfault.tgz -- the machine I am faxing from is a Canon IR3300 printer/copier/fax, but I get similar crashes from $29.95 fax machines too. :-) I'm trying to get a decent backtrace but

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

I'm trying to send a fax to my asterisk box, however shortly after connecting the fax machine reports a "communication error" and hangs up. Below is the error I get from RxFax: Fast carrier training failed Nothing is written to the file system as far as the tiff is concerned. Any ideas on how to fix this?

Hi all, I would like to announce the availability of an initial test version of a totally software FAX facility, suitable for use with Asterisk. This is a first public test release, so don't expect a solid polished product just yet. People have shown interest in what I am doing, and here is the evidence that it is not vapourware. If the notion of a software FAX machine is new to you,

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

Like some others on the list spandsp is segfaulting asterisk when recieving a fax. I'm on debian testing/unstable with freshly checked out asterisk CVS and sandsp. My libtiff version is 3.6.1. Here is the GDB output --- snip ----- Changed from phase 5 to 4 Start rx document - compression 2 Start rx page >>> CFR: 84 HDLC underflow in state 5 Post trainability Changed from phase

On the /proc/zaptel it was lost interrupts, you haven't got any so that's good! On opencall.org there's a known issues link and that mentions some fax machines that have issues, might be worth a quick check there. I can receive from our fax machine this end, if you'd like I'll send you a test fax if you send me your fax number, if you can receive from us and tpc then it's

Hi, spandsp-0.0.2pre18 works fine for txfax with HT488(version-1.0.1.2), but rxfax doesn't work. After some FAX sounds, it hangup! Could someone tell me how to debug?

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.
