Mic Click

Hello:
I'm looking for a way to send a sound bite thru an open mic channel. I've written a communication utility and the final step I need to do it send a 'mic click' sound prior to closing the mic channel.
In other words, think of this utility as a walkie talkie, and when you release the transmit button, a mic click is sent to the other person prior to the mic channel closing. I have the sound bite cued up and when I release the transmit button, it immediately plays, but I can't figure out how to send it down the wire to the other person.
Ideas PLEASE!!
Thanks for any help!!

Post some code, so we can see what you're doing

Im just guessing wildly here... its internet based? You have a client and server? Good: So send a message to the client to play a certain sound. You dont have to actually transmit the sound.
