Many thanks, Avi ! The following code worked for me: local ob_session = freeswitch.Session("{return_ring_ready=true,execute_on_answer=lua ob_answer.lua}" .. called_id,session) if (ob_session:ready()) then freeswitch.bridge(session,ob_session) else --- process failure here end All channel data related to the bridge and both legs are available from ob_answer.lua via session:getVariable() All the best / Mike ----- Original Message ----- From: Avi Marcus Sent: 07/15/11 01:48 AM To: FreeSWITCH Users Help Subject: Re: [Freeswitch-users] non-blocking bridge in Lua Some options: You can set an execute_on_answer on the leg B to run your new lua script http://wiki.freeswitch.org/wiki/Variable_execute_on_answer 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. -Avi Marcus On Fri, Jul 15, 2011 at 1:31 AM, Mi Ke <http://mi.ke @http://null.net > wrote: 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 ?
