[SR-Users] var vs avp...

[Carlos Ruiz Díaz]

Use $var when you want to manipulate values inside a route block, for
example, when you want to store a value that will live only in the scope of
that route block. When the route block exits, it will be automatically
deallocated.

Use $avp when you want to store a value that you want to read anywhere. It
will live as long as the SIP transaction lives.

- $var is stored in private memory, it is per process. This means that only
the process that created it can read it.
- $avp is stored in shared memory. It can be accessed from any process in
kamailio's process list (childs)

- $var has local route block scope.
- $avp has SIP transaction scope.

- Both $avp and $var are automatically freed.
