but I have no clue in how to interface this into asterisk.  I thought I
would put this link up for other people to comment and try.

Out of the box it works with soundcards.  I've been battling jack and
alsa for a week trying to get them to play nice just to reroute the
audio but I'm out of time in this regard.  So I thought I would toss it
up and see what other people can come up with.

Happy Holidays!

Linmodem doesn't work out the box with anything. linmodem was abandoned by its author at a very early stage, before any of its component parts really worked.

It has a number of useful bits, which might be used as the basis for a modem. It does not have a properly working code for any of the modem standards.

I think Fabrice got busy, and with patent issues preventing wide deployment of a V.34 modem finished the software just seemed like a waste of time to him. He is one of the good guys of free DSP, and has since produced several valuable things which are complete.
