similar to: Broken faxes when other call disconnects

Hello, I'm trying to receive faxes with asterisk. My configuration is like this: PSTN fax -> ISDN -> Cisco router with VoIP module -> Asterisk When I try to send a fax from PSTN fax I got the standard fax signal, Asterisk starts rxfax application and then call ends and there is no tif anywhere. On the fax display there is still one message: Calling... Part of my extensions.conf:

Thanks for the information Lee ! Still, something is still strange to me, since this two Panasonic Fax machines are receiving at least 20 multi-paged faxes a day (they are in same office as both Asterisk boxes, and me :) ). Beside that, POTS lines in those two faxes are from same PSTN switch as line in X100P in one of Asterisk boxes, and the ISDN PRI lines in other Asterisk box is from same PSTN

Hi everyone ! I have some aditional info on problem with TXFax and sending multi-page TIFFs. I have made 6 different multi-page TIFFs (Group3 1D with fillbits EOL aligned - 3 pages one TIFF in lowres and one in hires, Group3 2D -3 pages againg in both resolutions , and Group 4 - 3pages in both resolutions), and then tried to send them to Panasonic KX-F1100, Panasonic KX-F500 and SpanDSP

Just this week, I've installed an Asterisk solution for my current job, to replace a single POTS line which was shared between voice and fax. Before we go fully live with the solution, we need to come up with a solution to what to do with the current POTS line. The company is very keen to retain the line (or at least the number) as it has been in mail signatures, etc, for the past year or

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

I wrote a week or two ago about a problem I was having with a TDM400P with 2 FXS. The problem was reliable fax transfers. There were often slow or had communication failures during transmission. Richard replied to my post and told me this is an ongoing problem that might have a solution in the weeks to come. However, I was wondering if anyone had any alternate solutions for faxing with an

Why is using ulaw or alaw an unlikely scenario? I wouldn't use anything but ulaw\alaw. The Bells can compete on price and will if they have to. Where they CAN'T compete is quality. If there were something better than 711, I'd offer that. Well, there is 722, but not many things support it. ---- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ----- Original

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

Hello, I'm trying to do call forwarding based on this: http://www.voip-info.org/wiki/view/Asterisk+call+forwarding In the extensions.conf file I have several context defined (local, longdistance, mobile, international and so on). Each user can be associated with different context (so can make only i.e. local calls). How to set calls forwarding only to numbers that are available in

You have no dial-peer telling the router what to do with the outbound call. http://www.tape.net/~gerry/asterisk/cisco26x0.html At 12:50 PM 9/26/2003, you wrote: >Like Gerry wrote for callerid you need VIC-2FXO-M1 card. > >Right now I am stuck on making outgoing call. > >Could soembody help me with the configuration. > >On cisco I have soemthing like that: > >dial-peer

I have googled until blie in the face, WiKi'd until physically exhausted and searched through every Asterisk repository that I can find, all to no avail... No matter which version of SpanDSP I use, with which version of libtiff, Asterisk, ... I simply cannot send faxes. I can receive faxes *perfectly* (sending from standard fax macine on POTS) into tiff file (via Digium analogue card),

I've just made an interesting observation that I'd like to share with you all: the popular Sipura SPA-2100 just doesn't seem to be as great as I'd hoped. I've been trying to get inbound AND outbound faxing working via Asterisk and at least one of my termination services: Voicepulse or Sixtel. In general, inbound has been working flawlessly but outbound has been pretty

Hi, I'm putting together a fax solution for my company that utilizes T.38. I wanted to throw out my plan and get some feedback if anyone is doing something similar or sees a blatant problem with it. We're currently rolling out SPA-942 phones for the standard desk phone with vanilla Asterisk 1.4.15 (just upgraded it today) on the back end. Most calls for satellite offices are handled by

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.

Hello, I have spandsp working with asterisk (tested on one PSTN fax machine). Today someone wanted to send me a fax, but there was a problem with the TIFF file. This is what asterisk console says: TIFFReadDirectory: /var/spool/asterisk/fax/1140608321.7.tif: cannot handle zero number of strips. MissingRequired: /var/spool/asterisk/fax/1140608321.7.tif: TIFF directory is missing required

I've got a Digium Wildcard TDM410P with one POTS line and three extensions. One of the extensions is connected to a fax modem. This kind of works, but there's a gotcha. If I set faxdetect=incoming in chan_dahdi.conf, then incoming faxes do get routed to the modem and this all works, but outbound faxes fail, with a message like this: [Oct 29 21:57:09] WARNING[16732][C-00000000] app_dial.c:

Hi all ! Let's say you have about 6 small different companies sharing the same E1 / Asterisk server, and every company needs its own fax number. Since they don't really need fax machines, what would be the most cost-effective way to handle this (keeping fax-privacy at its best) ? Is there a way to configure Hylafax or sth & one modem behind an ATA-186 to email faxes to different

Hi, I tried to use txfax to send several faxes at the same time. It seams, that one can't send more than 3 faxes at once, or one risks to get 50% and more aborted faxes due to errors. The CPU usage is below 97%. I tried with Opteron and IntelP4: same result. Ok, I know, that faxing via a digital line is complicate, and I shouldn't complain, but I would like to know, whether these are

I'm proposing to install an Asterisk PBX at a collocation facility for a remote customer. Each of the customer locations will have an SPA-3000 with the FXO port connecting a POTS circuit and the FXS port connecting a fax machine or red phone. In addition to voice traffic, the customer has a high volume of incoming and outgoing faxes. Would it be possible, using g711 between the SPA-3000

Hi Guys, I've configured a fax support in my system with opensource app_fax/spandsp 0.6 - but there is a problem - if FAX transmission got interrupted - system permanently returns "The call dropped prematurely" - and no fax is submitted. This is sometimes very inconvenient, say if someone have sent a multipage fax with 20 pages, and it got interrupted on 19th page, the person will
