There is an event you can send to break playback just like you would  
sendmsg to the event socket to execute a playback.  I don't recall the  
exact syntax, could someone please update this page:

I think it will, but why don't you lab it up and test it and let us  
know.

You can probably do this by parking the ua2 and using the eavesdrop  
app on ua1 to spy on ua2.
