[Freeswitch-users] How to execute lua script on register?

[Dušan Dragić]

I agree with Ken, there are better ways to do this.

Maybe off topic:
I noticed a bug with how the hook event subclass string (in lua.conf)
is compared to the event subclass. For example
subclass="sofia::register" matches sofia::register,
sofia::register_attempt and sofia::register_failure event subclasses.
Also something like subclass="ia::register_atte" works (matches
sofia::register_attempt)

Looks like it's searching for a substring. I should probably open a jira.
