Its a card made by Quicknet, specifically designed for VoIP work.  There's
a couple of models, but they all basically do the same thing.  They
interface to either a phone or a phone line and handle all the call
control on the board.

They have really quick DSP chips that do all the codecing of the audio
stream, echo cancellation, and DTMF tone decoding.  They also have onboard
ring generators and the DSPs can also generate call progress tones
(busy..ring..dialtone..etc).
