Hi, I'm fighting with HylaFAX, Asterisk and T38Modem since some time, to get fax2mail and mail2fax working, my SIP-provider only supports T38 and thus using G711 with IAXModem is not an option. I have got running mail2fax with HylaFAX+ 5.5.0, Asterisk 1.4.20 and T38Modem 2.0.0 successfull, but I'm not able to upgrade to anything newer than Asterisk 1.4.24. I was able to break down this

Hi! I'm trying to get t38modem working and started with the loopback mode. I installed everything according to http://www.voip-info.org/wiki/view/T38modem+configuration+with+Asterisk and used a stock asterisk 1.4.20.1 compiled from source. Openh323, ptlib_unix and t38modem are compiled from source as well, as outlined on the wiki. Hylafax starts sending the job (sudo faxstat -s shows one

Hi, I'm trying to get T.38 passthrough to work to T38Modem and Hylafax so I can terminate T.38 faxes from an ATA. However I haven't had much luck. I've tried two supposedly T.38 capable ATAs, the Grandstream 206 and the 502. The 286 seems to connect to T38Modem, but Hylafax doesn't get any fax data. The 502 never even gets fax tones from Hylafax, so it seems like its t.38 is broken

Hi, I am trying to fix a Asterisk setup with buggy (POTS) Fax machines. The setup consists of the following components: - A Digium TE121 for connectiong to E1 ISDN - Debian box with Asterisk 1.4 - Grandstream GXW-4008 SIP ATA to which the Fax machines connect I am aware of the problems with this type of ISDN <-> Asterisk <-> SIP ATA <-> Fax machine installations, e.G.

Hi All, I know that this may not strictly be an asterisk issue, but if anyone has any ideas on this prob it would be appreciated. I have a working asterisk setup using Suse 9.1, a BT ISDN BRI card (Fritz?), sipura 3000 and a few cisco 7940's. I wanted to do add faxing into the equation, so I thought I would try and setup the following: PSTN->asterisk->hylafax->pc At the moment

Hi, I've read this thread in this list history http://article.gmane.org/gmane.comp.telephony.pbx.asterisk.user/261151/match=t38modem http://sourceforge.net/tracker/?func=detail&aid=3337581&group_id=152230&atid=783657 Has anyone been successful when integrating latest version of Asterisk (10 or 1.8, for instance) with t38modem ? My target setup is: fax ---<PSTN>-- SPA3102

Is it possible to use openh323's t38modem with asterisk and spanddsp? or would hylafax have to be thrown into the mix? If it is possilble how would I go about getting astersik to see it?

Hi, I'm trying to use Hylafax without a modem. Is it possible to use t38modem to make Hylafax send and receive fax via Asterisk? If yes, how? I'm searching on internet but still haven't found anything useful. TIA GIorgio Incantalupo

Hi all, I'm installing Hylafax on my Asterisk system. From what I've read, I can either use IAXModem or T38Modem to provide the virtual fax device. So at the risk of starting a religious war, which one should I use? I don't mind running IAX if I have to. I want as much flexibility and stability as I can get. So, what are your recommendations? Mike. -------------- next part

Dear gods of the PBX (flattery works here, right?) - I've been pulling my hair out trying to get Asterisk to receive and decode a fax using spandsp and app_rxfax. It seems like it should be working. The fax machine on the other end connects and Asterisk reports a fax coming in. But when it's done all I have is a 2 or 3 KB TIF (see attachment). The console activity looks completely

Hi, folks. I'm having a heck of a time trying to get outgoing T38 faxing (I don't need inbound right now) working with FFA and Gafachi. G711 faxing works (as well as can be expected over the internet), but I want the higher reliability of T38. I'm running Asterisk 10-beta1. When I drop my callfile in to make the call, I get this: -- Attempting call on SIP/18884732963 at

Hello! I'm still trying to get a working t.38 configuration w/ pjsip. I'm now able to send t.38 faxes to my own extension: hylafax -> t38modem -> extension -> extension -> t38modem -> hylafax. The fax is sent by t38modem. The receiving part of t38modem accepts the call, sends ReInvite for t.38 and things are working as expected. Now, let's do the nearly same

*Update Jul 2007:* For a T.38 gateway you can use Asterisk 1.4's T.38pass-through support in combination with the new OPAL (Open Phone Abstraction Library) - using t38modem (currently CVS) which now supports SIP (and not just H.323) to terminate T.38 calls. You can also use OPAL and chan_woomera to do essentially the same. Where can you find this t38modem stuff ? Google replies things that

Hi, I hope you might give me some hints on how to find where my configuration is wrong, I am new to Asterisk and do not know, how to find the problem. Running Asterisk (version: 1.8.13.1~dfsg-3) on Debian Wheezy. On the same maschine: Hylafax fax server. I want hylafax to use t38modem (a virtual T.38 modem) for sending faxes. t38modem schould connect to asterisk on the same host. If hylafax

I am looking at T38Modem. A relatively new version is ready for someone to build an rpm for (Mar '07). But the readme warns: Q. I try to use T38modem, but after run "t38modem -p ttyx0" I get a message "Could not open /dev/ptyx0: No such file or directory". A. Looks like you don't have legacy PTY devices compiled in your kernel. You need to re-compile the

Hello folks, I've been trying to get T.38 over SIP working with calls terminated by a MAX/Lucent/Ascent TNT. As far as I can tell, SIP and T.38 are actually working perfectly; however, I can't get the TNT to properly terminate a FAX call. Does anyone have a working configuration for SIP and T.38 for calls from a TNT or APX? Here's a brief description/diagram of my test setup:

I want to install Hylafax+, IAXmodem, and T38modem on my Trixbox 2.4 which is built on Centos 5.1 ("vmlinuz-2.6.18-53.1.4.el5"). Over at http://sourceforge.net/project/showfiles.php?group_id=148904 there are Hylafax+ rpms for: Fedora 7,8 Fedora Core 2,5,6 Redhat 7,9 I **think** Fedora Core 6? IAXmodem is only available in source at

The bounty stands at $5,500. I'm seriously considering taking a shot at it if I can find a decent T.38 provider to test with (I'm still hoping for reliable PAYG T.38). It looks like a lot of very smart people have done a lot of very hard work (t38modem, spandsp) that would go towards getting this working. At this point it appears to be mostly a matter of integration
