[Freeswitch-users] lua startup scripts (possibly!)

[Pete Kelly]

David, thanks for the reply.

I've actually decided to do this within an openser dialplan lookup before
the freeswitch media box gets hit.

However, it would be useful if there are any docs/examples around of how to
listen for and modify events using a lua startup script.
