[asterisk-users] Priority based softhangup

[Danny Nicholas]

AIUI, softhangup is strictly an address-type function.  Using Steve's
suggestion, you could set a key with the priority at dial-time and when a
congested condition occurred, match the database for the lowest priority to
hangup. Something like this:
Exten => 100,1,noop(prioritized dialing)
Exten => 100,n,Set(callpri=${DB(Callpri/${EXTEN})})
Exten => 100,n,Dial..
Exten => 100-CONGESTION(softhang.agi,${callpri})

Softhang.agi is a program you write to see if the callpri is high enough to
cancel another call and dial or send back a message.

In Asterisk, a "priority" is the "step number" in a dialplan. For example:

 	exten = *,5,	verbose(1,foo)

"5" is the priority.

It sounds like you want to have an "executive" class that can step on an 
"underling's" call. Maybe setting a global channel variable or tracking 
resource usage in a database would work.
