[asterisk-dev] Asterisk 16 Parking Lot Full behavior.

[John Kiniston]

If you are using parking hints you can query the state of the hint and see
if the highest numbered spot is available.

ExecIf($["${EXTENSION_STATE(709 at parkedcalls)}" = "INUSE]?Playback(lot-full))

It resembles a virtual memory manager in many ways. With the new parking lot in Asterisk 13+ supporting templates and creating a parking lot on-the-fly, I wanted to try to eliminate this complexity since it would reduce our complexity quite a bit.  So I suppose we could go back to that, but I'd rather not if possible.

I could see simply just playing a message to the parkee when the call is full, and using whatever the timeout behavior is set to.  Alternatively if Asterisk simply returned the call to timeout behavior, and possibly set a channel variable like to indicate the lot is full, we could then play the message or do whatever was appropriate.
