[TriLUG] RE: Phone to use with PC

OK.  As you mention: "I already have software that does what I want in the
MS-Windows world" -- you already have this working.  My bad.

It's clear I am not "getting" what you have running now in your non-Linux
OS.  I was having a hard time imagining where you plugged your mic in and
where you plugged your speakers in if not to you sound card, and how you get
them to run full-duplex without feedback, while processing the audio across
the PC to transfer to the modem card and then out to the phone trunk line in
some way.  I don't have an M$ application that does this, myself.

I think you misinterpret my response.  I too am an electrical engineer
besides a computer engineer, and I understand this a lot more than I
described.  The purpose of my simplified description was to prevent others
from suggesting solutions that are out of scope from what I am looking for.

Also please note -- forget any hardware modifications!  My modem already has
the capabilities (as do a lot of current modems), as I already have software
that does what I want in the MS-Windows world.  What I want is to replace
that software with an all-Linux solution.

P.S.  I used to work on the Lucent Bell Labs Conversant team that had
special hardware "tip-ring" boards used for the Conversant IVR (Interactive
Voice Response -- those "dial blah for sales, ..." audio menu applications)
and the Intuity Audix voice mail system.  What I thought was great in 1995
was that our DSP's were so good that we could detect and generate fax GNC
tones, and accept user spoken vocal or DTMF response while playing back
audio segments.  In other words, our voice-mail boards could double duty by
emulating modems and faxes.

In this application I am talking of, it is purely using the simple modem
board in my machine.  Like I said, it already works; I just want it to work
in a different operating system.  And I know that there are folks in the
area who have run into this as a hobby before.
