Yes, it is possible to make such a software only fax that can eg convert between g.711 and either t.38 or something that software like hylafax can connect to via a pty. Some of the work has been done as free/open software, but it would probably take as much more work to tie it together into a single project. The real problem is that the telcos that generated the standards tied everything up with patents, so something that can be released as source is hard to generate. I have seen ad copy (found via google) suggesting the there are solutions out there for what the OP wants to do. It would not surprise me at all were they as expensive as the cisco option, just for software to run on a linux or bsd box. But perhaps someone does have something priced at a (near-)comodity level. I doubt anything is available (yet) that speaks iax/iax2, but sip or h.323 should be supported. Just make sure it can take a g.711 call and act like a fax machine; and take a bitmap and generate a g.711 call to send that document. If all you can find is a g.711 to t.38 solution, openh323 has support for t.38 to eg hylafax. A bit of a rube-goldberg, but it ought to work. The biggest issue with these kinds of setups is latency. The fax protocols, as you can imagine, have latency requriements that are more stringent than voice calls. As a final note, modern fax machines have finally started supporting v.34 and v.34bis fax. HP's latest and imediately previous lines of office jets are an example. They also support a 300 dpi colour mode that, if I understand correctly, is no longer proprietory-per-vendor. It would be useful to have support for the higher dpi and faster modes in any g.711 software fax products. -JimC _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
