[asterisk-users] Fax over IP ?
Hi all, Couple of things I would like ask, does Asterisk provides free license for FoIP (for 1 channel) or need to purchase it? Couple of years back, I was able to send and receive the fax using Digium T1 card, in term of FoIP how can I able to receive fax from traditional telephone lines / T1 lines? As far my understanding, the functionality for FoIP is to send fax to email or receive fax from email i.e. using T.38 protocol. The thing I would like to know how I can implement this solution i.e. receiving fax via IP? Correct me if I'm wrong, while receiving fax from traditional telephone lines will the topology looks like as listed below; PSTN Lines -- Asterisk (mounted a T1/ analog card) -- IP -- Asterisk (receive Fax over IP) or else?

FoIP typically means the fax session traverses an IP link at some point, most commonly at the 'last mile'. What happens to the fax after that is up to your requirements. The faxes can be emailed out, stored in a web application, printed to a printer, etc. The possibilities are endless. Asterisk does have a few options for faxing. Those are most notably: 1. Fax for Asterisk - Free license available for 1 channel, or paid licenses for 2+ channels 2. app_fax (I think this is the current module name) - Free fax module for Asterisk, no channel limit, based on SpanDSP 3. Hylafax+ and IAXmodem - Most complicated method of fax setup, but most robust and reliable (in my testing). Would require use of Asterisk 10 with T.38 gateway functionality for proper fax reception. Just keep in mind raw fax audio over VoIP is a bad idea, see here: http://www.soft-switch.org/foip.html If you can provide some additional details on what you're planning to do, we can give more info. --Tim -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Can Asterisk receive a fax over a POTS or ISDN line ?? Do I then need a Digium TDM-card and an FXO-module or a T38-gateway ? What phones should I use to automatically configure them from a central place via HTTP or FTP ? I know Polycom-phones offer this option. How can I implement intercom functionality ? Which phones have auto-answer ? And how do I implement this in the Asterisk dialplan ?? I'm used to working with Asterisk 1.4. I hope the above is possible in an 1.4 environment.

[asterisk-users] fax over ip
I have an trixbox system setup, and all my phones are IP based, different Grandstream phones to be exact. I have some fax machines that are still around, using analog lines of course. I've read a little into FOIP and the changing of the signals form t30(traditional fax machines) to t.38 ( ip faxmachines). From what I understand, it's alot like voip, with origination and temrination. Can someone recommende, i guess, a FOIP provider? someone that can provider the gateway services?Also, how am i supposed to get my fax machine onto my ethernet network? i assume it needs some kind of Aanalog Telephone Adapter, just like with VOIP. Any info is appreciated , this is still clewgy to me.___ --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
Re: [asterisk-users] fax over ip
Christopher, Also, how am i supposed to get my fax machine onto my ethernet network? i assume it needs some kind of Aanalog Telephone Adapter, just like with VOIP. You need a T.38 capable ATA. There are a few but not too many. I believe the Grandstream ATAs have T.38 support or will have it (Support transparent Fax pass-through and in the future T.38 (pending)). The Linksys/Sipura 2100 can definitely do it -- it works well for me :). Then you need a T.38 capable ITSP. Some are listed on http://www.voip-info.org/wiki/view/VOIP+Service+Providers+T.38 but I don't have experience with any other them. T.38 pass-through support in Asterisk is available as a patch on the bug tracker for 1.2. Not sure if it made it into the 1.4 beta version or not, but on 1.2 it works OK for me. --Luki ___ --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
Re[2]: [Asterisk-Users] Fax over IP doesn't works
Dear Steve, SU So how does the FAX get from the fax machine to the T.38 channel SU with spandsp? In our case we will try to strip spandsp and will use directly OpenH323. We do tests for compatibility with one of the biggest national telecom and if they are OK, they will offer Asterisk based IP PBX to their clients instead Cisco. That's why we need of T.38 and G.711 fax capabilities. Also we have the problems with the following tests: 1. When Dialing of unallocated number the resposne must be Invalid Number, but the result is one of the following: Hangup, Congestion or Busy. 2.

Re: [Asterisk-Users] Fax over IP doesn't works
Hi Miroslav, It sounds like you don't really understand what T.38 is. You need some form of modem to get from a normal FAX machine to a T.38 channel. spandsp can do that. A normal FAX modem can do that. You need a modem somewhere, though. That is why developing the FAX modems was the first step towards providing T.38.

Re: [Asterisk-Users] Fax over IP doesn't works
We used spandsp on the voip side. Our inbound vendor sets the call up G711 and spandsp answers. It's a bit slow as it seems to only negotiate v29 terbo, but it works. Finding the correct version of libtiff was a pain. One sub version off, and it wouldn't work. Wasn't so much that it was a hard to get it to work, just a lot of tweaking to get it to work. Tedious.

The recent libtiff security patches should fix most of the libtiff issues, I hope. Why so many people have timing problems has still to be resolved. Some have been misconfigured E1s/T1s, but there seem to be plenty of others. There is nothing I can do about that within spandsp. spandsp on the VoIP side will always be a little flaky, I'm afraid. There is little I can do about that either. Building spandsp was actually a step towards T.38. That is why I have not been too interested in a HylaFAX interface (although one is in progress).
