We are currently testing a commercial fax library with the goal,
to implement an IAX client as fax server, in order the send or
receive some dozen faxes simultaniously. It is too early to
say, if we'll succeed, but we hope so, and thus won't forget
faxing through asterisk.

This is _no_ announcement of a product, since we currently
won't have the right to distribute the library, but we think,
it would be very interesting to know, whether it works or not.
Those, looking for a GNU licenced tool will have to wait for
progresses of spandsp anyway.


The audio path between the DSP and the PSTN really cannot be over any sort of a medium that will experience a frequent variance in the latency. So IAX is okay as long as the network will not "jitter". This is possible, and is especially possible when talking about a short, short IAX connection over the loopback device. If you involve any traditional "VoIP" medium (like an average LAN, WAN, or the internet), then the likelihood of the medium's variance in the latency will cause data corruption to occur... and depending on the frequency and timings of that data corruption will influence the likelihood of that data corruption causing a fax failure.

See:  https://sourceforge.net/projects/iaxmodem/

I'm about to release 0.0.2 :-)
