One thing that Kamailio does well is to take care of registrations and
everything related to this. If you get an INVITE you would probably want
to involve an Asterisk, at least when the call is not for one of your
local users (in Kamailio)
In this scenario Asterisk doesn't easily know about the users that are
registered to Kamailio. So Asterisk has to forward the invite to
Kamailio to learn if the user is reachable or not. Queues will work
differently because of this (no device states for agents).
Having device-states that goes from Asterisk to Kamailio is also very
useful. For example, if you have a conference at one of you asterisk
servers you can set the custom device-state for CONF_1234 to BUSY, and
you can have that end up in Kamailio.
