Thank you Michael, it works! Stephen On Thu, Jan 27, 2011 at 2:05 AM, Michael Collins <msc@freeswitch.org> wrote:

Use the eval API:

api = freeswitch.API() my_uuid = session:getVariable('uuid') ...

state2 = api:executeString('eval uuid:' .. my_uuid .. ' ${Channel-Call-State}') ...

The 'eval' API is useful for getting those "magic" variables that show up when you do the info app or uuid_dump xxx.

Hi, I have difficult to check the state of an originated session in lua script.

I want to know when the originated session is ringing back or progressing or answered.

I have tried with session:getState() but returns always CS_SOFT_EXECUTE.

My lua test script is called from dialplan with a:

<action application="lua" data="test1.lua"/>

And the "test1.lua" script is:

session2 = freeswitch.Session("sofia/external/xxxxxx@a.b.c.d");

while (session:ready() and session2:ready()) do state2 = session2:getVariable("channel_call_state"); freeswitch.consoleLog("warning", "State2 = " .. state2 .. "\n"); session:execute("sleep", "500"); end

if (session:ready()) then session:hangup(); end

if (session2:ready()) then session2:hangup(); end

This script fails because the session:getVariable("channel_call_state") returns nil.

What is the correct way to know the state of a call?

Stephen
