similar to: * T.38 fax

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

Hello ppl, Reading all over the net. Learnt quite a lot, but that has left me confused-a-lot as well. Need answers to a few questions. Before that, I have an ISP(fax gateway) which will help me send/recv faxes using the T.38 protocol. I am using Asterisk 1.2.12.1. Now to the few questions I had: 1) Do I need any additional hardware on the Asterisk box?? I did download the spandsp and

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)?

>I don't see why rxfax would be less reliable than iaxmodem/hylafax as >it's using the same spandsp to receive fax. I will defer to Lee Howard on this but IIRC the big factor is ECM which is not supported in SpanDSP. And another difference is that it is *HylaFAX* that is recieving the fax itself rather than SpanDSP. IAXModem just uses some of SpanDSP's libraries.

Hi all, I've run into 2 separate problems relating to fax: 1) Using tdm400p + fxo, Asterisk is unable to detect the fax from some fax machines (from others it can). Using zap barge, I can confirm that these troublesome calling fax machines _do_ send the fax tone loud and clear. Are there certain circumstances where I should expect a Digium card to fail in detecting a fax? 2) Using

Hey All, I've been trying to get SpanDSP / RxFAX to work in order to set up a soft-fax machine on my asterisk system. I have asterisk CVS-04/08/04-10:06:15 and spandsp 0.0.1. This is on a Fedora Core 1 with 2.4.26 kernel. I have tried to look for a newer version of the spandsp stuff, but opencall.org does not seem to exist in DNS any more. (If it's moved location, can someone please

Hi all, I'm trying to enable faxes on my asterisk box using spandsp version pre10. The outgoing and incomiong calls work great, but i have problem with faxes. The fax detection works, the RxFax application is called, but i only receive the beginning of the faxes (variable between 3 to 5 first inches of the fax). The output .tif file generated is then cut off. My setup is : asterisk

Hi, I've been trying to get fax going for the last few days. I can receive fax with Spandsp 0.0.2pre19 on Asterisk 1.0.9 with rxfax, but when I tried sending the received fax file to a fax machine, I either get "line error" or just a blank page. Is anyone using Spandsp to send fax to fax machines on PSTN? I've run out of things to try now, and I'd really appreciate if

Hi, I'm using spandsp-0.0.3 [http://www.soft-switch.org/downloads/snapshots/spandsp/ spandsp-20061116.tar.gz] on a bristuffed asterisk (1.2.13) [http://212.91.251.199/~junghanns.net/downloads/bristuff-0.3.0- PRE-1v.tar.gz] libtiff is at version 3.6.0 Running on: Linux router2 2.6.17-2-686 #1 SMP Wed Sep 13 16:34:10 UTC 2006 i686 GNU/Linux Debian testing distro. I've tried many

> Actually.. I seem to have jumped to improper conclusion.. One thing you will find abour spandsp is that some fax machines will just plain have a problem sending to spandsp, period. Mr. Underwood has localized it to cetain HP fax machines and I can confirm that HP all-in-one SOHO machines exhibit this problem, but I have also noted it with Canons and Panasonics. In my context, I have several

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 =>

Hello, I'm trying to receive a fax to my inbound number from voipbuster. Asterisk receives the call and starts the rxfax application successful, but then nothing happens. The calling party is still hearing a ringing tone, or sometimes nothing. Voicecalls are working correct and without problems. For testing I've add a local number (300) to the dialplan. When I call this number

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

Hey guys I was hoping I could get a few pointers on a problem I have been trying to debug for the last couple of months regarding asterisk AGI scripts and unexpected termination. I have this agi script that accepts incoming faxes using RxFax on the latest asterisk 1.4 branch. Its written with perl and it works fine except for one line that causes the entire script to terminate unexpectedly. The

Everyone, Just thought I would drop a line telling everyone here I have the software RxFAX/TxFAX up and running without any real problems. I did have to..... RH 9.0 1) Install an audio devel rpm 1) install libtiff from source, and copy over a bunch of include files to /usr/local/include 2) build/install spandsp 3) move app_rxfax.c and app_txfax.c to apps/ dir in asterisk source tree. 4)

Dear list, I need to setup asterisk to send and receibe fax. I just looking about SpanDSP, Hylafax/Iaxmodem, AsterFax,...etc. The asterisk box has Digium hardware, one TE420B and one TDM2402 (8 FXO ports). I just read the SpanDSP (txfax and rxfax) makes the system more unstable that Hylafax/Iaxmodem. And the Asterfax solution does dislike cause its licensing. The TE420B, is configured in E1

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

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

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

A DID number was dedicated to receive fax, but i have the problem when getting fax call, which call will become a normal phone call and no fax was printed. When fax is detected, the fax extension is executed and dial the extension of the HT486 device (firmware 1.0.5.22). Somehow sending fax out working well. In the mailing lists, i notice some are using HT286 and it work. Could someone share
