[Freeswitch-users] Help Needed Debugging Lua Script

[Avi Marcus]

Two things:
1) You aren't grabbing the arg, but the channel variable.. try this in your
script:
caller_id_number = argv[1]
number_to_call = argv[2]

2) I don't think you're managing your hangup/callback originate properly.
I don't think you want to use bgapi... or maybe you just need a
destination. It's "originate
<http://wiki.freeswitch.org/wiki/Mod_commands#originate> sofia/A endpoint"
-- you need to specify where it goes to, the lua script can't "receive" the
call. You can have it received by e.g: &lua(pickup.lua)

api = freeswitch.API()
api:execute("originate", DialString.." &lua(pickup.lua)");

Also:
Maybe you want to use it as a hangup hook. Instead of:
<action application="lua" data="callback.lua ${effective_caller_id_number}
${destination_number}"/>
Do:
<action application="set" data="api_hangup_hook=lua callback.lua
${effective_caller_id_number}
${destination_number}"/>
<action application="hangup" data="486"/>
