thanks for your quick reply. I'm not quite sure whether your answer
is really the answer on what I wanted to ask, so I'll clarify below.

I think to make sure that this is really what we need I'll have to
provide a better description of the problem. We are developing a
testbed for wireless voice transmission. We will have up to 16 active
phones, that are independently used to receive voice samples. We have
to record each voice transmission to a .WAV file (because this is what
the quality measurement tool understands).
To do this we will have to connect the 16 phones to a Linux box (prefered)
and need the ability to save the voice sample to a file. Each sample is
completely independent of all the other samples. Basically we need the
ability to do "sox /dev/phonespeakerX phoneXsample.wav" where 0 <= X <= 15.

Following your suggestion I glanced at jack. I'm not quite sure whether
this is really what we are looking for.

Thanks in advance
