[OpenSIPS-Users] $var scope clarification

[Bogdan-Andrei Iancu]

Hi Brett,

I see you missed the last webinar on script variables ;).

So, the $var() are script variables - you should not rely on any kind of 
persistence for them. They are intended to be used in script only (in 
route + all its subroutes).
You should use them for script ops (like iterations, building strings, etc)

This vars are not share at all and, as they are attached to processes, 
it is highly recommended to reset they value before using them in script.

Regards,
Bogdan
