Re: [asterisk-users] rxfax() problem - fax signal seems to be ignored
[RESOLVED]
Hello Andrew and thx you for your response, which led me to the solution.
You are right concerning the Ringing() and Answer(), so I put this out of my
dialplan.
The way to test with a std phone is a good idea, and permit me to hear the
spandsp CED tone. Very easy to do, and I'm still asking myself why I did'nt
though to that before :-)
This led me to the conclusion that the ||debug was in cause : when using it,
rxfax() answer a coming fax with a CNG tone instead of a CED tone.
I simply removed this ||debug argument, and now when I call the 300
extension, I can hear the CED tone like expected.
Using ||debug acts like if I had used |caller instead. Seems to be a bug.

Hello,
my configuration is the following:
a TDM400P board with an fxs and fxo daughter boards on it.
I thus connect a fax to my FXS port, after having verified that this
port
was correctly functioning. For this, I had tried before with a simple
phone,
and with some basic voicemail exten scripts.
Here is my simple dialplan for my fax reception:
exten = 300,1,Ringing()
exten = 300,n,Answer()
exten = 300,n,Set(FAXFILE=/tmp/test.tif)
exten = 300,n,rxfax(${FAXFILE}||debug)
Why? exten = 300,1,rxfax(/tmp/test.tif||debug) would do the same
exact thing. No need to indicate ringing and no need to answer the
call. Besides that it is just incorrect you are never going to have
correct answer supervision on an analog line, so don't even try.
I then dialed 300 on my fax machine, and expected to be lucky and to
obtain
a /tmp/test.tif file after faxing completion.
But instead, I always got such error in the /var/log/asterisk/full log
file:
What if you just use a regular analog phone and dial 300? What
happens? What if you remove the ||Debug from your RxFax dialstring?

Notice how your own logs prove that 0ms elapse between the time you
incorrectly indicate ringing on the channel and the time RxFax begins.
I have enabled the #define LOG_FAX_AUDIO inside spandsp library, and two
audio files (fax-rx-audio-b7933500-070905134224 and
fax-tx-audio-b7933500-070905134224) appeared in /tmp.
Just listen into the line. When you execute RxFax it will play fax
tones just as if another faxmachine answered -- not CNG tones
This is not the case in my setup. What did I wrong?
Thx for your help.
What version of Linux, Asterisk, Zaptel, SpanDSP app_rxfax are you
using?

Digium will not commit anything to the Asterisk code base that is not disclaimed to them first. They do this for various commercial purposes. They *could* take anything GPL, like spandsp or any related T.38 developments in OpenPBX, and commit it to a GPL-only branch of the Asterisk codebase, but then they would have features missing from their non-GPL licensed commercial offering. So yes, there is nothing to stop Digium from using GPL code in their GPL Asterisk ... except Digium stopping themselves.

What does Steve granting a license to Digium have to do with it? I don't care if Asterisk and the fax support don't come from the same place. First off, I'm not really the right guy to be having this conversation, but since I know enough of the facts I can respond accurately enough to satisfy your query. If you ask a lot more questions in the what-if direction I may have to bow out. Steve's related code is two-fold... code that is in spandsp and code that is in OpenPBX. And, actually I think that spandsp comes with OpenPBX, so it's really just one download. Anyway, spandsp is a library. You get it, install it, and you end up with a bunch of code libraries that really don't do anything by themselves. You have to have some other software that utilizes those libraries, like the well-known txfax and rxfax applications... or like iaxmodem. Steve's work in OpenPBX is not really something that you can extract out of OpenPBX and stick into Asterisk very easily. I guess you're welcome to try, though. And, if you become successful in that - in producing a patch to apply onto Asterisk and you then endeavor to maintain that patch along with all of the other patches that you have to maintain to keep your motley Asterisk running your OpenVOX cards, your txfax/rxfax apps, and the myriad of other things that don't come with Asterisk for who-knows-what reason... well, then you're effectively maintaining your own little fork of Asterisk. And at that point I would wonder why you have gone through all of that effort just to avoid using OpenPBX, which is where Steve put that code for you to use in the first place.

What does Steve granting a license to Digium have to do with it? I don't care if Asterisk and the fax support don't come from the same place. Its easy to maintain a well contained application, like rxfax, outside the tree. Trying to maintain patches to rtp.c, chan_sip.c and other core elements is too much of a pain to be reasonable. The code I contributed to Asterisk for T.38 passthrough languished for about 9 months before it was integrated. The day it was integrated it was in a less suitable state for integration than the day I contributed it. The patch to chan_sip.c had required many hours work from people over those 9 months, trying to keep up with the changes to the chan_sip.c in SVN. Its just wasteful and frustrating. The development of Asterisk has now degraded to the point where I will no longer contribute anything to it. If someone wants to take my code and make it work with Asterisk under GPL conditions, that's fine. The GPL gives you that right. Please make sure you stick to GPL conditions, though. You can't use G.729, for example, in an Asterisk that's using spandsp.

I really dont know rxgain = 12 makes that much distortion but I'm curios to know if I pass through the incoming fax to an analog fax machine on another fxs line, the machine wouldn't receive the fax too? Anyways, let me take the most benefit as im sure you'd read this post, i have problem with the size of received page which is shrinked, can u give me a hint about this problem too :) Thanks. --- M.

Shokuie Nia wrote: Dear folk, My problem solved after two day research and try and error method ;). It was related to rxgain of the board im using. I've set the rxgain to 12 and it seems made some problem. As far as I got the spandsp is so sensitive about noise on the line and because of that it couldnt hand shake with other side well. rxfax isn't sensitive to noise at all. At a gain of 12 you've caused overloading and distortion, and the signal cannot be decoded. Many people seem to be nearly deaf. They run systems at massive gain with awful distortion, and seem content until they find something like a modem or DTMF detection doesn't work too well.

Re: [Asterisk-Users] rxfax problem - libspandsp issue?
Here is a link to some known issues... http://www.soft-switch.org/spandsp-known-issues.html -Original Message- From: Roger Schreiter Sent: Thu, June 16, 2005 6:53 pm Hi, I just started my very first attempt receiving faxes by asterisk. Compiling, installing and setup went without problems. (asterisk-1.0.7, libtiff-3.6.1, SuSE-Linux 9.1) When receiving a fax also everthings seems to work fine, but the tiff file itsself is corrupted. Various tiff viewers do report errors (wrong line lengths) and finaly display a picture, which has nothing to do with the original. Did anyone encounter the same problem? Is it a version problem of libtiff? (libtiff-3.6.1 seems to be the most recent one, besides CVS.) Thanks for any hints!

Re: [Asterisk-Users] rxfax problem - libspandsp issue?
They keep breaking the FAX support in libtiff. 3.6.1 is broken, although a lot of distributions contain a patched version which works - usually because a spandsp user got the patch pushed into the distribution. HylaFAX users seemed to just give up trying to follow the buggy path of libtiff, and stick with libtiff 3.5.7 which seems to work reliably.
