[lug] Sound-enabled modem via Linux?

[Nate Duehr]

Actually what you probably want if this is a commercial application is 
something like a true telephony card, like the ones from Dialogic.  They 
can be bought in different port densities and they have analog phone 
line cards up through multiple T1 cards for voice applications.

Computer Telephony magazine is an interesting source to find out what's 
going on in that "world" also -- it's been years since I was involved 
with a project that did basically what you're talking about under Novell 
3.12 -- uggg... strange memories of that project are now crowding my 
mind.  :-)

Last I was looking at the stuff, Linux was making massive headway and 
there were drivers for a lot of manufacturer's stuff out, again -- this 
was a long time ago.  I'm sure the state-of-the-art in Computer 
Telephony has passed me by long ago, but I'd bet Dialogic and some of 
the others are still big players.
