It has been discussed many times, but since Asterisk is a  
multiprotocol PBX, we don't
recommend it and won't include it. What would you do if you forked a  
call to three
phones and got different results? And if one of the forks is not SIP?

There's a lot of logic to write, that we already have for the core  
hangup cause.
