Yes, but how can you distinguish the two. On a ISDN bus, in point to 
multipoint, all connected units will start ringing when there is an incoming 
call, for example. If the one phone sends a RELEASE_COMPLETE message to the 
NT, then the NT knows that the phone does not want the call, but the other 
phones are still ringing, and the user that is calling does still hear the 
ringing signal. But if you send a RELEASE_COMPLETE, with cause equal to 
Reject,

m(CAUSE_Q850_CALLREJ      ,=0x15, "call rejected")\

then all phones will stop ringing, and the calling party will also get a 
rejected message.

So again, why does asterisk not have "AST_CONTROL_REJECT" ?
