Soundcard Audio as Extension?

Is there a way of routing an extension to the soundcard? I would like to be able to transfer calls to an extension and have them hear the audio being fed into the line-in on my trixbox. Also have multiple channels be able to hear it. (not a busy extension when someone else is using it)


Trixbox may be trickier - I don’t know. But in a plain Asterisk, you simply use CONSOLE/dsp.
