[asterisk-users] Asterisk Faxing
Greetings! I have Asterisk 1.4.25.1 running as a Xen virtual machine using 64-bit domU and Dom0 with faxing and was curious about other users' experiences with it. So far receiving fax works just fine, but I'm curious if anyone else is doing international faxing with asterisk. If yes, could you please post your experiences? Were there any issues you may have encountered that I should be looking out for? Best regards, Martin W.

Re: [asterisk-users] Asterisk Faxing
I don't do international faxing, but I'll share these tidbits: Asterisk Faxing is a hit-or-miss proposition; either you're a genius or a fool (sometimes both in the same day). Faxing using POTS is a pretty simple proposition; SIP and T.38 add complexity to the equation. Simplification of the process as much as possible is as good as Tylenol. The timing on the VM may or may not bite you dependent upon the frame you select to use for outgoing (POTS, T.38, etc.). -Original Message- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Martin W.

Kyle, you are missing CPC on the line, asterisk is not detecting the hangup because your phone company is not giving it to you.

In any case, your statement is false. Digium is quite interested in pursuing more FAX (both TDM and T.38) support in Asterisk, and we are exploring options all the time. Steve Underwood and the other fine persons that have helped to develop the software DSPs and other stuff required for FoIP support also have no interest in writing any further faxing support for Asterisk (RxFax, TxFax + the newest span_dsp wont even compile, much less work under Asterisk any more) probably because they know it will never be included into the Asterisk code. It has not been offered for inclusion into the Asterisk code base; it would be willingly accepted if it was offered for inclusion. ___ --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

So as far as the desired contribution is concerned, there is nothing there that prohibits it from inclusion. The problem, however, as we all know, is that the Asterisk maintainer, Digium, requires undue retribution in the form of disclaimers before it will accept any contribution into the code repository - and in this case the author of the desired contribution is reasonably refusing. And that, I believe, condenses a vast portion of the frustration that the Mr. Joakimsen was expressing.

Undue? Yes, by definition, undue: unwarranted, not owed. The GPL on Asterisk, as distributed by Digium, affords the user various rights to use, modify, and redistribute. Part of the philosophy behind the GPL is so that modifications can - without further licensing - be returned and used by all users of the software, perhaps even being merged in upstream... and thus those that modify and redistribute repay the licensor in kind. In this case, however, the repayment in kind - per the terms of the licensing - is not enough for the licensor to accept. Digium requires disclaimers so they can dual-license it for ABE and other commercial vendors. Of course I know this, but maybe others reading don't. You should be able to understand why a licensee who makes a modification would not want to either sign a disclaimer or put their work into the public domain. You're purposely twisting and distorting the reality with these weasel words. Honestly, I'm not trying to be weasley or any thing of the sort. Nor am I trying to twist or distort the truth. Have I made a statement that is untrue? If you don't like it, use something else. Well, I do have several options, and I dabble in many of them as I dabble here. Know, however, that I only ever hear this kind of counter-productive suggestion here. There's no need to take jabs at the company. Really, I was not intending to take jabs at all.

RE: [asterisk-users] Asterisk Faxing Support
I find this surprising. Is this fact? I don't see faxing disappearing anytime soon. I'm surprised Asterisk/Digium would ignore it and not try to support it. If people are to replace their old PBX's with Asterisk faxing is almost always going to be required. We have an old POTS line for faxing but it would be nice to get rid of it. For Asterisk/Digium to drop supporting faxes seems odd and doesn't make good business sense. I know a lot of people that will simply not give up faxing because of legal documents. I believe it should be built in since every other PBX system out there does it. If Asterisk/Digium are truly trying to supplant legacy PBX's faxing should be included. My two cents (a nickel with inflation) I'm off my soap box for now. -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Andrew Joakimsen Sent: Monday, February 05, 2007 2:57 AM To: [EMAIL PROTECTED]; Asterisk Users Mailing List - Non-Commercial Discussion Subject: [asterisk-users] Asterisk Faxing Support Asterisk 1.2 has no support of t.38 whatsoever, the call will drop before t.38 is ever utilised, not even pass-thru. 1.4 Adds support for T.38 pass through only and no other sort of faxing, the endpoint must support T.38 and you must send your call to a T.38 gateway and you must not use NAT anywhere in your network and you must enable re-invites which could cause CDRs not to reflect the true details of the call.
