[Freeswitch-users] Wait for ANSWER/HANGUP events in Mod lua

[Karsten Horsmann]

Hi Sam,

you should be more verbose what you currently doing. There a many ways to
call an lua script in FS (in the dialplan, as startup-script, as
dialplan-binding etc).

Sounds like you want to fetch some kind of billing informations.
