[Freeswitch-users] Lua script with arguments called from Dialplan

[Petr Both]

Hi,

Thank you very much for confirmation.

This morning I made again the tests with

<action application="lua" data="TestArg.lua 3000"/>

and then also with

<action application="lua" data="TestArg.lua ${destination_number}"/>

and using the same script like yesterday it works fine now. Probably I 
had the FS in some inconsistent state, destroyed by non-sense 
modifications in DIALPLAN xml configuration.

So using now in lua script the code

freeswitch.consoleLog("INFO", "INCOMING START CALL * to FreeSWITCH, 
arguments from DIALPLAN " ..argv[1].." "..#argv)

it works fine. Btw. I have found also another way how to get the 
destination number in Lua script which is

local CgNumb = tonumber(session:getVariable("destination_number"))

which is probably the equivalent of the same variable delivered from 
DIALPLAN.

So thank you very much again.

Regards
Petr B.
