Using Asterisk to redirect sound output to VoIP

Hi, I am looking for an application that can act like a virtual sound card and send all workstation audio (that would normally go to the sound card and out a speaker) to a VoIP channel.

So, if I establish VoIP call using Asterisk to another computer, can I send all of the audio output from that workstation over that channel instead of to the local sound card?

Thanks,
Tony

You might be able to use app_jack for this.
