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? -- A human being should be able to change a diaper, plan an invasion, butcher a hog, conn a ship, design a building, write a sonnet, balance accounts, build a wall, set a bone, comfort the dying, take orders, give orders, cooperate, act alone, solve equations, analyze a new problem, pitch manure, program a computer, cook a tasty meal, fight efficiently, die gallantly.
