Summary:                    wait_for_answer never receives HANGUP frame sent via
ast_queue_hangup
Description: 
1) A user calls into our Asterisk pbx via one of our PSTN lines and dials
   a SIP extension.
2) The caller hangs up the PSTN line before anyone answers the SIP
extension.
3) Our channel driver calls ast_queue_hangup to inform Asterisk of the
hangup.
4) Asterisk never acknowledges the hangup and the call eventually times
out.
