I'm messing around with pre-dialer handlers today and running into a wall.
Dial has the U option where I can execute a Gosub when the channels bridge
and there I can set the variable GOSUB_RESULT to BUSY to make Dial act like
the channel I called was Busy.
I want to do something similar with a Pre-Dial handler but don't see a way
I can Set a variable or return a value that will cause Dial to act like the
channel I called was Busy?
Use case:
Endpoint 100 calls Extension 101
Extension 101 has a Pre-Dial Handler that checks how many calls Endpoint
101 has in progress and if it's greater than X returns a Busy.
Dial acts like it got a Busy back from the Endpoint, Sets DIALSTATUS and
continues through it's dial-plan.
I've tried using the BUSY() Application inside my Pre-Dial handler.
I've tried sending BUSY back as a Value with Return() to be picked up in
GOSUB_RETVAL
I've tried setting DIALSTATUS to BUSY.
Am I trying to use the wrong tool for the Job here?
Related, Why can we have multiple Hangup handlers but not Pre-Dial handlers?
