should be quite actual. As Matt said, we do have new features with more
recent releases 4.1.x and 4.2.x but the relevant parts in the relation
with Asterisk (authentication, registration, etc.) are more or less the
If Asterisk preserved pretty much its old realtime mechanism and
database structure, then should be straightforward to adjust in case of
I hope to get a new tutorial that uses latest Kamailio and Asterisk 13
in the near future, targeting to use ARI instead of database for making
the integration of the two applications.
