Some options:

You can set an execute_on_answer on the leg B to run your new lua script

Or, you can schedule all this stuff in the originate string, with either execute_on_answer or export nolocal:api_on_answer=sched_transfer or the like.

Hi all !

I want to make a Lua app which will start with Leg A, collect input, initiate outbound Leg B and when it answers, periodically play decreasing series of beeps to Leg A depending on how many minutes left to disconnect (remaining time queried via odbc).

My initial idea was to issue a non-blocking bridge command after Leg B session originate returns ring-ready and then to do the rest in while loop, but the bridge called by api:executeString("bgapi bridge legB_session legA_session") just returns Job UUID without actually bridging sessions. A usual freeswitch.bridge call blocks further script execution until unbridged, disallowing me to check Leg B states when it's active.

Is there any elegant way to acheive my goals using Lua/Dialplan apps ? To create an app starting with Leg A and constantly watching for Leg B existense/states, playing corresponding feedback messages to Leg A ?

Thanks in advance for yours hints/responses

Mike
