[asterisk-dev] How to reject calls

OK i see what you want to do. You don't want to send a
AST_CONTROL_REJECT, but you want to send a AST_CONTROL_HANGUP with the
hangup cause 15 which leads to a RELEASE_COMPLETE with reject cause on
the A - side. 


In ISDN you don't have something like DISCONNECT_REJECT and
DISCONNET_NORMAL, but instead you use the disconnect cause to specifiy
why you want to stop the call.
