similar to: Asterisk Faxing Support

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)

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)?

what method is preferred: haylafax and Iaxmodem or spnadsp for faxing. -------------- next part -------------- An HTML attachment was scrubbed... URL: http://lists.digium.com/pipermail/asterisk-users/attachments/20071228/e829632a/attachment.htm

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

I have asterisk with rxfax txfax modules.I want to test fax sendig and reciving in one asterisk instance, in extensions.conf I have : exten => 1234567,1,rxfax(/home/patryk/fax-new.tif|debug) exten => s,1,Dial(1234567) exten => s,2,txfax(/home/patryk/fax.tif|caller|debug) but I doesn't seem to work.But when I'm calling on this number I can hear fax tones. I can't find sip

Hi Steve and all, 1. Faxing from asterisk back to the same asterisk (from one Zap channel to another) doesn't work for us. Txfax called with the 'caller' parameter issues CED, while the receiving side needs CNG in order to switch to fax extension with rxfax. 2. This is probably the reason why J2 and our UC don't recognize incoming fax. Thank you. Alex Zarubin Webley Systems

Steve Underwood, Would you mind summarizing where/how T.38 functions, and maybe how it compares to the analog fax environment for the asterisk-users arhives? Seems to be some misunderstanding, and a lot of interest in handling faxes in various forms via asterisk. If some these approaches were summarized in one posting, a lot of us could reference it to remind us of limitations, current state,

Anyone knows where can I find spandsp? Official site seems permanently down... TIA, Simone.

Here is the setup: POTS -> PRI -> Asterisk -> ATA (Fax) The ATA is set to only 711. Asterisk's sip.conf sets this device to only 711. Yet, faxing works less than 50% of the time. I cannot possibly be the only person with this problem. I can't even get app_rxfax to work. It answers but rxfax drops the call 5 seconds into it. If anyone out there has near 100% success with

OK I see the ponit (although I never said that second page is interrupted - I said that in some combinations of resolutions and TIFF options receiving fax "spits" another blank sheet of paper beside the clearly received first page). I have read someware (some faxing tutuorial) that there is some kind of control code (6 EOLs I belive) that should be in TIFFs between pages and that

Hi list, Just installed spandsp. In my limiting testing, I have an issue on a Philips fax machine (HFC21) directly connected to my * server through TDM400, reception with rxfax works fine, but txfax always fails. Below is a transcript of failed transmit. This is with asterisk-1.0.3 (with native moh patch but I don't think it is the source of the problem). I already tried libtiff 3.5.7,

Hi, spandsp-0.0.2pre18 works fine for txfax with HT488(version-1.0.1.2), but rxfax doesn't work. After some FAX sounds, it hangup! Could someone tell me how to debug? The following is the * CLI> log to 192.168.0.161:43222 -- Executing NoOp("SIP/4881-bde9", "") in new stack -- Executing RxFAX("SIP/4881-bde9",

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

When are 'we' going to have this solution Steve? :) You keep talking about it, and we keep asking when it's going to come about. I know myself, SS7 will be a make or break for our continued use of Asterisk. Even if we had some price indications would be good, and/or a timeframe? Don't want to seem pushy, but it's been on the cards for quite some time now. Ben -----Original

1. What is the difference between Asterisk v1.6 RXfax/TXfax and Digium Fax for Asterisk? 2. Is Free Fax for Asterisk identical to Fax for Asterisk nonwithstanding the 1 channel limitation? 3. Can any purchase of Fax for Asterisk count as channel 2+, when used in conjunction with Free Fax for Asterisk? 4. When (If ever) is colour support likely? Michael

Hello, I have bought a targeta quadbri. I want to realize a PBX server to send and to receive fax on lines BRI. I have installed asterisk and the drivers of quadbri (bristuff_0.2.0-RC7b). I downloaded and installed the module spandsp-0.0.2pre10 When i send a fax from the fax machine to asterisk, the application rx_fax saves the fax in a file on the hard disk. The problem comes when I try to send a

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

I have already tried to contact to persons from Digium and I did not receive a response. I was wondering if there is any plan to support fully faxing in Asterisk, I.E.: A "T38 Gateway" of sorts.

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
