There is no code to do that. What whispering does require though (for 
both Chanspy and Snoop channels) is a constant media stream out to the 
channel. It's likely that in the specific scenario there is nothing 
generating a stream and thus nothing to whisper into.

There's an open issue[1] to remove this requirement but I know of noone 
currently working on it.
