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

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

>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

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, 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'm proposing to install an Asterisk PBX at a collocation facility for a remote customer. Each of the customer locations will have an SPA-3000 with the FXO port connecting a POTS circuit and the FXS port connecting a fax machine or red phone. In addition to voice traffic, the customer has a high volume of incoming and outgoing faxes. Would it be possible, using g711 between the SPA-3000

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

I am testing out hylafax and iaxmodem. Submitting jobs to the hylafax server and having it then dial using iaxmodem is working fine. Hylafax server is talking to my Asterisk box that has a Sangoma A101 in it via iaxmodem via an IAX channel using ulaw. A call coming into a certain test DID comes into the Sangoma A101 then it goes to another box via IAX ulaw that uses the rxfax app to

Hi all, After a long time having no time, I have finally done some fresh work on my software fax machine. I have replaced the original carrier tracking with something more robust. I have also added 4800, and 2400 bits per second modes, and cleaned up a few bugs in areas like superfine mode operation. I apologise for this update taking so long. At ftp://ftp.opencall.org/pub/spandsp you will

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)

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

Hi, thanks for your answer. Unfortunately this is, what I already know. I was wondering, why it is possible to set ID and Header for an outgoing fax (which will then in turn be inserted via asterisk on top of the transferred "image") , while it seems to not be possible to get the Header from a received fax (only the id), although it is present in the faxdocument. The ID is also

Hello All ~ Having problems sending and receiving faxes with SpanDSP. I am testing on a simple 2 analog POTS to 2x X100p set up, connecting one line to a Konica 720 fax machine to test, or with other remote fax machines. Voice calls are working pretty well now. Platform is P3/800MHz/256MB/FC1. * recognizes faxes, and passes calls to RxFax and TxFax OK, but 99.9% of the time no fax content is sent

Hi! I am struggling around with * and the spandsp library (app_rxfax) for a couple of days. I'm trying to receive faxes which come via a SIP gateway. The rxfax-module answers the call, the reception of faxes, however, still does not work correctly, the received file is only about 300 bytes of size, because the sending fax machine is terminating the transmission. Now I've figured out

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 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

Greetings, All-Knowing Asterisk Users List, My company needs to build a reliable fax server that can handle at least 30 simultaneous incoming faxes from the PSTN, using PRI. We realize that this can be solved in any number of ways using a Linux box, but since IVR is also a must, Asterisk popped up as the most promising solution. After combing these lists for clues, we began experimenting

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

I just want to pdf and email faxes coming in over pstn on a TDM400P. Outgoing faxes would just go out over pstn, not through asterisk. All the voipinfo , etc, howto's are quite complicated. And most use third party apps like Hylafax. I thought there was a rxfax and txfax in 1.4. And 1.6 had app_fax. I'm now using 1.4.22, but I'd go to 1.6 if it made this easier. But I've
