[asterisk-dev] How to reject calls

this RELEASE_COMPLETE should not create a AST_CONTROL_HANGUP on the
A-Leg (incoming call) (B-Legs are the ISDN Phones Ringing).

Exactly this RELEASE_COMPLETE should create a AST_CONTROL_HANGUP with
cause 0x15 on the A-Leg

So for what situation do you need the AST_CONTROL_REJECT Frame else for?
