[OpenSIPS-Users] A few simple general question

[Nick Khamis]

Hello Everyone,

Just a few quick questions:

1) Is there any core variable that returns the IP destination of where
the SIP packet is going. For example, 192.168.2.20 in:

U 2013/05/26 19:26:14.807995 192.168.2.10:5060 -> 192.168.2.20:5060

$si: 192.168.2.10:5060
$di: Return the destination of the incoming packets (i.e., the
interface of OpenSIPS)

2) When to use CR vs. DR, is one a subset of the other. And finally,
which will be more likely to stand the test of time?

Thank you for your time,

Nick.
