Well, I've never seen dialplan like that - is this a very old version of Asterisk, or psuedocode?
Anyway.. A subroutine MUST be balanced, and if a subroutine is aborted before it reaches return, you'll be in all sorts of hell. An example: You make a subroutine of some sound files you want to loop through to make an IVR menu. You call it using Gosub. Someone presses two while the third of 5 tracks is playing. The stack will then be unbalanced and you'll then be in a potential world of stack overflow and unknown hell. So keep the gosubs for things where they cannot be interrupted. Playback is fine. Background and ControlPlayback is not. See? Here's a solution to this problem which caused me HUGE amounts of headaches early on (and I mean days and nights on end!) Hope it helps... https://github.com/lardconcepts/asterisk-pbx-tips-and-snips/blob/master/gotchas-and-warnings.md On 21 March 2017 at 17:31, Ethy H.
