[Freeswitch-users] Execute HTTP request from LUA script not work

Thu Aug 23 09:17:24 UTC 2018

Hi,

Not sure if this helps, but as far I knew you need to use Lua version 5.2,
not 5.1

https://freeswitch.org/confluence/display/FREESWITCH/mod_lua

Since FreeSWITCH 1.4, you need to use Lua5.2 (http://www.lua.org/manual/5.2/
> ).
