Dear list, I got this scenario. FAX Machine -> FXS (tdm800) ->Asterisk -> SIP <-> OPENSER <-> SIP -> Asterisk -> FXO(tdm400) -> PSTN -> FAX Machine I' been reading a lot of Faxes and t.38 protocol... and I found that Asterisk 1.6 has the possibility to do FAX t.38 Gateway funtion...and also that CallWeaver (Asterisk Fork) also has this feature. Has anyone have experiencies on this kind of scenario... what version?.. patches?... or any information regarding this goal will be VERY helpful... Ing. Arturo Ochoa N Electrosystems S RL Tel.

In the scenario above the FAX Machine at the end would be obsolete. The open issue would be the conversion between analog fax and T.38 fax. Does anybody has a smart solution how the following could be achieved? - Detect incoming analog fax (from PSTN) - Translate incoming analog fax to T.38 - Transmit fax per IP to another box (maybe a long distance) - Translate incoming T.38 fax to analog fax - Terminate fax on a normal analog fax machine With this scenario it would be possible to use the old fax machine you already have, but also use reliable fax transmission over IP. -- Tobias Wolf Softwareentwicklung / Kommunikationsl?sungen Evision GmbH Wittekindstr. 105 44139 Dortmund Tel: +49 (0)231 - 47790 307 Fax: +49 (0)231 - 47790 500 http://www.evision.de This electronic mail transmission and any accompanying attachments contain confidential information intended only for the use of the individual or entity named above.

I think there is still a bit of confusion as to what termination and gateway and Asterisk 1.6 is all about, capability, functionality, call flow to what application, library requirements, spandsp versioning..... And when do you think we can expect to see stable solutions for each. Thanks. JR

Termination would be an incoming T.38 signal comes in and gets interpreted at the server. and Gateway would be when you have a signal from a fax machine that the server then converts to a T.38 signal (as in the T38Gateway app in callweaver). Or am I missing something?
