asterisk users - Jul 2007 - exit ChanSpy with DTMF

Part of a supervisor menu I'm writing requires that I allow the
supervisor to choose to ChanSpy a channel from the main menu then return
back to the menu to choose other options when she's done.  Is there a
way to 'exit' ChanSpy and continue down the dialplan?  Or is a caller
stuck in ChanSpy until they hangup the phone?

Thanks.
George

Any thoughts?  Am I stuck with modifying chanspy itself to allow an exit
DTMF?
