[Asterisk-Users] 911/Emergency calls + Caller ID

In my experience, the 911 dispatcher can (does) pin the call, so that 
even though the remote side hangs up, the line is not available for use 
again until the dispatcher releases it.   I'd expect this to mean that 
the proposed "hangup" would end up with the 911 operator transferred 
from caller->caller->caller if asterisk were configured to re-use a line 
for a new outbound 911 call...
