Can I make asterisk refuse to transfer one outside call to another (or 
ask for confirmation first) without disabling transfer to an internal 
number?  The problem is that the user had no idea he had flashed, (he 
hung up quickly and thought he had disconnected the first call and 
didn't notice the stutter dialtone) and wasn't trying to bridge the 
calls, so he didn't realize he had tied up two outside lines.  Once 
someone did this on two overseas calls.
