Hello,
I'd setup a test environment where Kamailio accepts external invites and routes them
to an internal Asterisk (actually working as an SBC).
My dialplan works fine routing the INVITE to the internal Asterisk, but the SIP message
goes into the defaul sip context (the one configured in sip general), and not in the
context defined for the sip trunk between Kamailio and Asterisk.
Well, first you are
on the wrong mailing list... Asterisk questions is better handled in Asterisk forums.
If you turn on SIP debug and the core debug level, Asterisk will tell you how it is
matching and how it
is searching in the list of peers and users.
The first error I spot in your config is "type=friend". You should
ALWAYS use type=peer for Kamailio trunks.
So hit the console, turn on debugging, find out what goes wrong in matching the peer and
you are on your way.
/O
The sip trunk is configured like this:
[kamailio]
disallow=all
host=kamailio
port=5060
insecure=port,invite
type=friend
context=from-sip-external
fromdomain=mydomain
qualify=yes
allow=alaw
allow=g722
So I expect that all the sip invites coming from kamailio should be executed in
from-sip-external context.
But it doesn't work like this since each invite goes in the default context.
The invite that goes to Asterisk is like this
<--- SIP read from kamailio-external:5060 --->
INVITE sip:extension@asterisk:5060;transport=UDP SIP/2.0

What I think is that in the sip message there is no information about kamailio internal
ip address but only about kamailio-external address and then Asterisk put it into the
default context.
If this is the reason, should I change the trunk ip address in Asterisk and should I do
some manipulation on the incoming packet on kamailio?
Or maybe I should use kamailio-external as fromdomain in the trunk configuration?
Thanks.
