[Freeswitch-users] Lua Script with mod_vmd, setInputCallback doesn't seem to get called

[Michael Collins]

I haven't played with events inside Lua yet, but here's an example:
http://wiki.freeswitch.org/wiki/Examples_directory_lua_asr_tts

Look at the onInput() function in that example. There it gives the syntax
for extracting the event header to see what event type has come in.

The other question I have: did you confirm that mod_vmd triggers properly
when going to this mailbox? You could write a simple dialplan that sets
mod_vmd, calls the phone, sleeps for 10 or so seconds, and then dumps the
var ${vmd_detect} to see what it says. I've used mod_vmd from the XML
dialplan with a fair amount of success, although to my knowledge I never
actually tried it with a Verizon wireless VM box.

Confirm that mod_vmd works with just the dialplan before trying to debug the
Lua script.
