Play a Chanspy stream as music on hold?


I am looking for an unusual feature: I want to play a chanspy stream as a music on hold in a queue.

This is similar to enter in a conference, but I want the callers listening a specific conversation in live but not participate and waiting in the queue.

My idea with the chanspy is to proceed like a radio stream, but I don’t see how can I create a real time wav file with it…
