I recognize that you're being a bit facetious in this latter comment, but the argument that you're making here is unfounded. I believe that if you were to look at the Davidson Consulting reports about the fax industry for as long as those reports have been available you'd find this. The technology is not dead and has enough momentum to propel it forward for many years to come. Maybe this is understood in your acknowledgement of society supporting it, but the reason why it's supported is because the technology is sound and fills a very valuable purpose in business and other activities. There is no adequate replacement for fax. E-mail doesn't do it, and most other reliable document communication mechanisms are locked-up in proprietary patents and interests that will invariably prevent them from becoming standardized at all. I'm not a big T.38 fan-boy, although I do applaud the ITU for that attempt to get fax working on IP networks. Unfortunately, it's fundamentally flawed because it needlessly perpetuates the tether between fax and telephony. In an IP network there is no reason whatsoever for fax to be saddled on top of a telephony layer. Fax is data communication, and IP networks are quite effective at data communication. I can envision a future fax system which truly uses modern IP network designs such as DNS, encryption, security, and rides on a very effective communication protocol and yet continues to operate on the fundamental communication protocol defined in ITU T.30 which makes well-implemented faxing so dependable. I can't count the hundreds of hours I've wasted on fax support just to prop up this stupid and unnecessary technology. Many others have felt exactly the same way, and I don't mean to be rude, but invariably the reason why they feel this way is because they repeatedly tried to do it the wrong way. We just made the decision this week to outsource it all and never deal with it on our network again. I am slowly re-gaining my sanity because of that decision. And until the new technology comes along that is and will be *precisely* the right decision for most of the people who move to a virtual environment or who completely detach themselves directly from the PSTN. Now I'm going to take a fax machine out to the parking lot and shoot it, even talking about this awful waste of time makes my blood boil. Well, if you were using stand-alone fax machines then that was part of your problem. Thanks, Lee. -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] FAX via Asterisk
Hi, I am also looking for a fax solution. I use Cisco ATA adapter with fax machine and sending of fax works perfectly. But receiving fails after call is answeredby the fax machine. It may be a problem of the fax machine also. The configuration is simple. I use CISCO SPA 112 – 2 Port Phone Adapter. First connect an anlog phone to the adapter and dial the number given in the manual. You get an IVR menu to configure IP address. Once IP address is configured you can get into the web interface and configure it just like any other SIP extension. Then map the fax DID to that SIP extension in the extensions.conf. Thats it. But here my problem is receiving dont work. Patrick, can you please give the steps to configure fax with iaxmodem and hylafax. Is it free to use?

Once a fax is received it is emailed to whatever you configure. Sending faxes works too in libreOffice. If you have a bunch of DIDs you could give people their own direct line and fax number.

Be absolutely sure you have your Zaptel/DAHDI timing settings correct so all ports are sync'ed properly with one timing source. Also, ensure your telco is giving you a real TDM circuit/path, not a TDM port that is serviced by a VoIP connection. Many companies are doing this now as it cuts their costs significantly for service delivery and works fine for voice but you'll have problems galore trying to get a modem/fax carrier working reliably. They'll usually call this product a 'flex T1' or 'Mega T1' or some other marketing-hype type name and give it a lower cost. You don't want to walk away from these products, but rather, run as fast as you can. :-) I've used the Rhino channel banks extensively and they work very well. In fact, a recent installation was specifically for combined voice/fax/modem usage and it performed perfectly. The only difference in my case versus yours was that the T1 was being provided by the telco, not via a T1 card in another Asterisk box. But again, assuming you have your timing setup correctly, this should work very well. --Tim -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Hi! 'Fax for Asterisk' is a commercial application sold by Digium. This is not their official support channel. Since you paid for the product, why not contact them directly about your problem? Maybe because having to deal with Digium support is an ... uncomfortable experience that I've made twice. It really feels like a support avoidance system, and you are an unwelcome guest that should please leave as soon as possible. I really hope that Digium takes steps to a) make their behaviour less bureaucratic when establishing a support call (try to do that on behalf of a clue-less customer of yours and you know what I mean). Also my feeling is that b) the level of competence (or familiarity with the product in question when it comes to software prodcuts) could use some improvement. If you take a look at the Digium web forum for Skype for Asterisk, for example, you will see that any kind of half-official answer or helpful reaction from Digium's side is by now non-existent - most probably due to internal policies. This just doesn't feel right, and many other companies haven proven that I can be done differently. Philipp -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Re: [asterisk-users] Fax throughput - Asterisk 1.6.1.9
Cyprus VoIP wrote: Yes. I saw the message and the required addition in the sip.conf. The problem is that if I set it to 72, other terminating gateways that support 400 or more would also be limited to 72. This is incorrect. First, you would not set it to 72, since the endpoint is already telling you 72; you would set it to something higher. Second, as the documentation states (and my email stated), this a minimum threshold. It does not override the value provided by the endpoint unless the provided value is *lower*. All of this you would know if you had already tried it, which probably would have taken less time than writing the two emails about it have taken :-) What doesn't make sense is Asterisk's commission. Why doesn't it simply pass/use whatever it gets without cutting the values? It looks like it's a bug. It is not a bug. Asterisk has to deconstruct incoming UDPTL frames when they are received, pass them through a bridge, and then construct new ones on the outbound side. To do this, it has to have knowledge of what the maximum IFP size each endpoint can receive is, and compute a reasonable T38FaxMaxDatagram value to tell the *other* endpoint (taking into account the error correction mode(s) in use) so that when it receives a UDPTL frame from endpoint A it can be reasonably assured it will be able to forward it to endpoint B without violating endpoint B's max datagram size... but when endpoint B has told Asterisk a ludicrous max datagram size, it must be overridden somewhere to allow FAXes any reasonable chance of working. Alternatively, I could (had I known how ;-)) set this ATA not to relay the RTP via Asterisk, in which case maybe Asterisk would leave the values unchanged. When I use another port on this ATA from the same location to the same destination without passing through the Asterisk, the faxes go through. How should I define this peer in sip.conf so that Asterisk wouldn't relay the RTP for it? T.38 FAX can use RTP, but almost never does; in all of the cases you are dealing with, it is using UDPTL for media transport, not RTP. Asterisk does not yet support direct UDPTL media between endpoints, so that's not an option for you. That's not necessary, though, because clearly when you tell those two endpoints to talk directly to each other, the one that receives 'T38FaxMaxDatagram: 72' is *ignoring* that restriction and sending larger packets... it has to, or the FAX would fail. Asterisk doesn't do that automatically, for safety's sake, it tells the administrator when this problem is occurring and how to overcome it. -- Kevin P.

Cisco gateways generate T.38 SDPs that do not conform to the T.38 recommendation in one very obvious (and painful) way: they tell us that they can only accept 72 byte packets (T38FaxMaxDatagram), when in fact they can accept packets much larger than that. When you notice that they are also requesting that we use t38UDPRedundancy for error correction, that means that the maximum IFP (single FAX protocol packet) we can include in a UDPTL datagram is around 30 bytes, since we'd need to have room for two of them and a bit of overhead. 30 bytes is a ridiculously small limit for IFPs, and does not allow successful FAXing at any possible bit rate (except for 2400 bits per second using 10 millisecond IFPs, but no FAX stack would do that).

Re: [asterisk-users] Fax throughput - Asterisk 1.6.1.9
Hello, We upgraded the Asterisk to 1.6.1.11. Now, there's no RTP reINVITE, but the datagram handling of Asterisk is strange. Basically, it takes a commission from both ends, and ends up overflowing: Reminder, we're dealing in this example with a passthrough, where we have an ATA device connected to Asterisk in the same LAN, the Asterisk is registered to a remote SIP Proxy server and behind it, a Fax server. This is the reINVITE SDP received from the SIP Proxy: --- Content-Type: application/sdp Content-Length: 353 v=0 o=root 30427 30428 IN IP4 194.98.xxx.xxx s=session c=IN IP4 194.98.xxx.xxx t=0 0 m=image 17548 udptl t38 a=T38FaxVersion:0 a=T38MaxBitRate:14400 a=T38FaxFillBitRemoval:0 a=T38FaxTranscodingMMR:0 a=T38FaxTranscodingJBIG:0 a=T38FaxRateManagement:transferredTCF a=T38FaxMaxBuffer:72 a=T38FaxMaxDatagram:72 a=T38FaxUdpEC:t38UDPRedundancy --- Asterisk sends this reINVITE SDP to the ATA device (notice that the datagram was reduced by 2): --- Content-Type: application/sdp Content-Length: 269 v=0 o=root 31812 318120001 IN IP4 192.168.2.10 s=Asterisk PBX 1.6.1.11 c=IN IP4 192.168.2.10 t=0 0 m=image 4427 udptl t38 a=T38FaxVersion:0 a=T38MaxBitRate:14400 a=T38FaxRateManagement:transferredTCF a=T38FaxMaxDatagram:70 a=T38FaxUdpEC:t38UDPRedundancy --- Then, it gets OK SDP from the ATA with the same settings it suggested: --- Content-Type: application/sdp Content-Length: 275 v=0 o=101 01 02 IN IP4 192.168.2.11 s=A conversation c=IN IP4 192.168.2.11 t=0 0 m=image 9100 udptl t38 a=T38FaxVersion:0 a=T38MaxBitRate:14400 a=T38FaxRateManagement:transferredTCF a=T38FaxMaxDatagram:70 a=T38FaxUdpEC:t38UDPRedundancy a=sendrecv --- But, when it sends the OK SDP to the remote end, it lowers the datagram again: --- Content-Type: application/sdp Content-Length: 275 v=0 o=root 936220937 936220938 IN IP4 xxx.xxx.xxx.xxx s=Asterisk PBX 1.6.1.11 c=IN IP4 xxx.xxx.xxx.xxx t=0 0 m=image 4650 udptl t38 a=T38FaxVersion:0 a=T38MaxBitRate:14400 a=T38FaxRateManagement:transferredTCF a=T38FaxMaxDatagram:65 a=T38FaxUdpEC:t38UDPRedundancy --- Then, when the ATA device sends T.38 packets, it freaks outs: --- pbx*CLI Got UDPTL packet from 192.168.2.11:9100 (type 0, seq 0, len 86) [Dec 15 12:38:05] WARNING[5262]: udptl.c:997 ast_udptl_write: UDPTL asked to send 77 bytes of IFP when far end only prepared to accept 12 bytes; data loss may occur.

I saw the message and the required addition in the sip.conf. The problem is that if I set it to 72, other terminating gateways that support 400 or more would also be limited to 72. What doesn't make sense is Asterisk's commission. Why doesn't it simply pass/use whatever it gets without cutting the values? It looks like it's a bug. Alternatively, I could (had I known how ;-)) set this ATA not to relay the RTP via Asterisk, in which case maybe Asterisk would leave the values unchanged. When I use another port on this ATA from the same location to the same destination without passing through the Asterisk, the faxes go through. How should I define this peer in sip.conf so that Asterisk wouldn't relay the RTP for it?

Hi all,
just to explain you that finally I've achieved it to work :)
Many thanks to all and sorry for asking about issues I could have found in
documentation.
2009/9/9 F6HQZ f6hq...@hamwlan.net
exten = _8XX,1,Dial(${SIPPROVIDER}/${EXTEN:1},,G(fax-tx^send^1))
This dial command line call a FAX number through a SIP provider and, when
answered, give the hand to the macro who has in charge to realy send the
fax.
Good luck !

just another stupid question, as far as I know, when a call is answered

it's hung up, which execute h priority, so how can I make it execute a
SendFAX, or whatever else, when it's answered?

That’s the general idea. The application is designed to send a TIFF
over an established connection. You can detect that it is a fax or just
assume so.

Hi everybody,
I've installed Free Fax For Asterisk in my Asterisk box but I don't
understand how it works as when using SendFax application from dialplan, I
can't find how to introduce destination fax number.
How this application works? Do I have to call destination fax using Dial
application, detect somehow that it's a fax and then use SendFAX application
specifying FAXOPTs and the path to the fax file?
Many thanks

Re: [asterisk-users] Fax For Asterisk and SendFax question
exten = _8XX,1,Dial(${SIPPROVIDER}/${EXTEN:1},,G(fax-tx^send^1))
This dial command line call a FAX number through a SIP provider and, when
answered, give the hand to the macro who has in charge to realy send the
fax.
Good luck !

thanks Danny,
just another stupid question, as far as I know, when a call is answered
after Dial application, it doesn't execute other dialplan priorities until
it's hung up, which execute h priority, so how can I make it execute a
SendFAX, or whatever else, when it's answered?

Subject: [asterisk-users] Fax For Asterisk and SendFax question
Hi everybody,
I've installed Free Fax For Asterisk in my Asterisk box but I don't
understand how it works as when using SendFax application from dialplan, I
can't find how to introduce destination fax number.
How this application works? Do I have to call destination fax using Dial
application, detect somehow that it's a fax and then use SendFAX application
specifying FAXOPTs and the path to the fax file?
Many thanks

Re: [asterisk-users] Fax for Asterisk - Fax routing based on TSID
Receipt of the fax could be handled in the manner you describe using something like Ghostscript to parse the partial file into pages as it came in. Sending the file is pretty much an all or none proposition unless you did something funky like splitting the file into chunks and sending in consecutive sessions. I'm pretty sure FFA doesn't let you say send 123 etc. -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Karl Fife Sent: Tuesday, July 07, 2009 10:02 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [asterisk-users] Fax for Asterisk - Fax routing based on TSID I'm using Fax For Asterisk, and trying to optimize the user experience while ROUTING faxes based on the Transmitting Station ID [sic] (NOT the CALLERID). Specifically I'm trying to eliminate end-user confusion as that fifty page fax spools to a file, creating a significant delay, leaving the user to wonder why am I not getting my fax--they said it's currently sending. A better user-experience would be to begin TX'ing the fax (at the same or slower speed than RX) after a page or two has been spooled as a buffer. If I'm using SendFax from the dialplan it appears that I would need to spool an entire incoming fax to file (to completion) before I could route said fax based on the Transmitting Station ID However if I were to drive the fax process from manager rather than from the dialplan, would the TSID be available for read before RX completion, AND (equally important) would sendfax even tolerate sending a fax from an still-spooling RX file? In other words, does the application require that the spool file be complete and closed before it would allow you to begin paying it out 'from the top'?

I don't think that the current FFA applications will do what you want. Even if you could somehow manage this, any delay in the receiving process could cause it to get 'behind' the sending process, which would then abort due to an incomplete file. That's even assuming that the SendFAX application will accept an incomplete TIFF/F file in the first place :-) Even with FAX gateway support you wouldn't be able to achieve this, because the gateway outbound link would be setup before the TSID is received. What might be possible is to have a page-per-file mode, so that as each page is received it is stored in a separate file; you could then watch for 'received page' events and transmit the pages that had been received up to that point. I'll do a bit of research to see if this is possible. -- Kevin P.

I have an TDM800P+ata+fax and work fine. This setup take 5 min. The best solution must be hylax fax + asterisk. But you need an asterisk specialist to make the setup and take more time.

Re: [asterisk-users] Fax with asterisk
ATAs work OK I guess, just make sure to use a loss less codec such as ULAW. Personally, I would install a single port FXS card in the Asterisk server to avoid any IP transport. You may have to mess with the gains to get it working very well, but nothing beats your existing POTS line. If you had many physical fax machines and a spare T1 port, I would suggest a channel bank, this has worked on par with a POTS line in my experience, providing you are getting PSTN access through a T1/E1.

Just to clarify, pika's chan_pika is their asterisk channel driver for their

are fax modules for asterisk to implement fax in your dialplan:
exten = 5001,1,Answer(1000);
exten = 5001,n,Set(LOCALSTATIONID=123456789)
exten = 5001,n,Set(LOCALHEADERINFO=PIKARxFax Test Page %P Time: %H:%M To:

exten = 5001,n,Set(FAXFILE=/tmp/pikafax-${UNIQUEID}.tif)

Forgot to mention (I think) that though the chan_pika driver is for pika
hardware, the two fax apps for asterisk work with 3rd party hardware as
well, so you don't actually need the pika cards (that's why it's nice and
easy)

Re: [asterisk-users] Fax with asterisk
Hi Erik, once we used grandstream ATAs but now we are using linksys models: it has better design (look is important too for customers) and has 2 ports for two analog devices. We tested it with PRI and BRI lines and it seems working fine! Giorgio Incantalupo Erik Haider Forsen wrote: Hi Giorgio, Thanks for your answer. Your setup is exactly what we're thinking of.

Hi The kernel timer shouldn't be relevant. The timing should come from the card, and not from ztdummy. Make sure that the timing comes from the card and not from ztdummy. I don't load the ztdummy module, so timing is taken only from the card. The only reason I put rtc in my kernel is that I was looking for a solution that helps to improve the timing, but unfortunately this didn't help at all. What is the target of the fax? Fax from where to where? From PSTN to faxserver (the one I described in my previous email) and from faxserver to PSTN. Outgoing way works fine, but incoming faxes work only when the remote machine is another fax server; when it is a traditional fax machine the quality is very poor.

In my case, I have a single PRI coming into a single port PRI card on my Asterisk box. My old fax numbers (prior to our switch to PRI) are DIDs on that PRI. Using IAXModem+HylaFAX, I can recieve faxes without having seperate POTS lines for faxes, or an external fax board, or a multiport T1 card.

But you're right to point it also has drawbacks ... saving the dedicated line is the biggest one, the next notch is what about when you have busy periods of 5min a month, do you get a second dedicated fax machine, fax line, hunt group etc ? we just give out line 2 in our hunt group as the fax number, have autodetect on the lines in asterisk and switch to the fax extension (channel bank with faxmodem and hylafax) when a fax comes in. this gives us an incoming fax pool as well with no extra line cost. This actually works fairly well through a channel bank even with all the extra d/a a/d conversion going on. We plan to try the soft fax channels as well but have not tried that yet. if someone has problems (pretty rarely), then we tell them the extension of the faxmodem to dial, we also have a real fax machine on another extension we have them try calling. That always works and the extra switching does not impact the faxes themselves. The biggest issue is remote does not talk to usr faxmodem, but will talk to a real fax machine, nothing about the asterisk detection and switching usually matters. we have never done it yet but the faxes could use all the lines at night for mass faxouts or certain lines or whatever since its all connected that way already anyway. lots of the benifits are not possible with a dedicated fax line. as for the drawbacks you could make a lot of the same arguments about voip in general but people still use it anyway. forgetting about voip and virtual channels and asterisk for a minute, why is it so hard to find a faxmodem that actually works as reliably as a physical fax machine ? Should be simple, but I guess it will eventually lead to it just becoming software only when the hardware manufacturers can't get it right. ___ --Bandwidth and Colocation provided by Easynews.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users Jon Pounder _/_/_/ _/_/ _/ _/_/_/ _/_/ _/_/_/_/ _/_/_/ _/ _/ _/_/_/ _/ _/_/ _/_/ _/_/ _/ _/_/ _/_/ _/ _/_/_/ _/_/ _/_/_/_/ _/_/_/ _/_/ _/_/_/_/ Inline Internet Systems Inc.

I searched extensively on this and did not find anything conclusive except the general understanding that on TDM cards every instalation is different whereas for BRI /PRI it should work. As for the config, Asterisk just works perfectly well with voice conversations over the FXO line. I add one IAX extension in * for the IAXModem and then in the IAXmodem configure the default modem as the one that is registered in *. If I make a Fax call to my mobile, it rings and I can hear the Fax on the other side. So, the problem I believe is in the negotiation/sinchronization where something is broken at some point. I would like to know wether it is possible to solve this adjusting some parameter in some config file or I should just forget it and use a digital line instead. Thanks, Jose L.

Thanks, Steve I know Fax is not officially supported on TDM400P cards but I did not expect not being able of sending one single Fax. Actually when I try to send a Fax, the call is established between my * server and the remote Fax but after 30 secs Asterisk disconnects the call and Hylafax reports NO CARRIER DETECTED. Tried playing around with a few parameters such as no echocancellation, alaw (also slinear) codec, faxdetection =incoming in zaptel but with no luck.

Re: [asterisk-users] Fax with Asterisk + Hylafax
You could try to get it working but it may never be 100%. If your needs are 100% then I suggest using a standard fax and get an analog line and do it the old fashioned way. If you need Hylafax type features then buy a modem that is compatible with Hylafax and run it on a different box. Just suggestions.
