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 ---<T38>-- Asterisk with t38mode...

Hi all the people in the list! I'm new on this list, this is my first post. I configured asterisk 1.6 with freepbx 2.7 and dahdi to send faxes with t38modem conected to hylafax as a sip extension of asterisk. Everything is supposed to be configured fine, the faxes start sending, but at the middle of the transaction, it fails. The T.38 termination provider told me that they were receiving a=T38MaxBitRate:2400 on their asterisk, and told me that this iss...

...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 asterisk and hylafax are on the same box. I went and installed t38modem, hylafax, openh323 and so on.... got chan_oh323 compiled and installed. I can now dial an extension - it gets routed to t38modem, it picks up but I hear no modem tones (screeching) just silence. when I dial it with a fax machine the fax machine just says 'no carrier'. Looking at the hy...

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 -------------- An HTML atta...

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 thing, but use an ISP: hylafax -> t38modem -> extensi...

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...

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 Aste...

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

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 leg...

...ly 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: Laptop --RS232--> Modem --POTS--> Channel bank (ADIT 600) --CAS T1--> TNT --Ethernet/SIP--> Asterisk --SIP--> t38modem. The TNT is running TAOS 11.0.4 with both the SIP and realtime fax features licensed. I've tried using several modems, and with each I can establish a data call without any problems (although at a maximum of 31200bps/3429 baud using a 33.6 modem, for reasons I haven't dug into yet.)...

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 sends a fax it should use t38modem which ist connected to asterisk. Asterik is expected to establish an outbound connection to my SIP provider which supports T38. The asterisk box is behind...

Hello,

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 Hylafa...

Hi, Do you have any example showing how to use SendFAX ? I can see several examples of ReceiveFAX but not a single one showing SendFAX.

...iff-3.5.7) I've tried multiple sending fax machines and get the same effect. Any tips on getting this setup working? I've run out of ideas. Alternately, I'd also be willing to offload the DSP processing to a HylaFAX machine using some sort of software fax driver. I tinkered with t38modem and chan_h323, but couldn't get it to do anything once the HylaFAX machine answered. So if anybody has any experience with that, I'd be interested.
