Hi list, I'm running current SpanDSP http://www.soft-switch.org/downloads/spandsp/spandsp-0.0.4pre6.tgz with Asterisk 1.2.22 somewhat successfully. Most Fax machines do work but I have problems with people having Tobit FaxWare and Shamrock CapiFax. http://www.tobit.com/login/mrd.asp?CategoryID=120 http://www.shamrock.de/ I've got black bars over the pages. In Tobit some content is Ok, other is covered by the black bars. Anyone else has simliar problems? I talked to Tobit and they said there should be an option somewhere in SpanDSP to disable Fax header crossbars. But I found none. Can anybody help me with this issue. Please no "switch to Hylafax" mails, because I'm very happy with SpanDSP, it integrates nicely and works most time. Thank you, Regards Christian Peter

I haven't heard from anyone using tobit or shamrock software (who on earth wants to call their company tobit? weird). I have no idea what fax header crossbars might be. Do they have some kind of bicycle integration in their product? :-\ Is your problem when sending from Asterisk or receiving? Can you enable debug and e-mail me a log and (assuming its a receive problem) the resulting TIFF file. Steve

Can I use SpanDSP and Asterisk to handle incoming (and possibly outgoing) faxing? Is there a howto or some notes somewhere? I have seen the SpanDSP code used in the fantastic OSLEC echo canceller but have not seen it referenced anywhere else? Cheers Alan -- The way out is open! http://www.theopensourcerer.com

It handles faxes outside Asterisk when used with iaxmodem (there is actually a copy inside the iaxmodem package). SpanDSP cannot be used by the standard distribution of Asterisk, as it is GPL code. However, if you are using Asterisk within the restrictions of the GPL you can add app_rxfax and app_txfax to Asterisk quite easily. Regards, Steve

The issue is that since Asterisk is dual-licensed, GPL-only code cannot be included in the mainline asterisk source. SpanDSP is (to my knowledge) GPL-only and hence, cannot be included. -Dave

The issue is that the code has exceptions to the GPL, to allow it to be linked to certain patented codecs, for example, without violating patent licenses or the GPL. SpanDSP, on the other hand, is not dual licensed, so you cannot run, for example, both G.729 and SpanDSP in the same binary (legally), since the pure GPL license of SpanDSP "pollutes" the Asterisk binary to require the same of the G.729 codec (which is not permissible until the patents on G.729 expire). -- Tilghman
