Check what's in line 392, it should give you a hint what's wrong.

I'm also not familiar with the default kamailio config, but presence
itself has nothing to do with IM per se. There are two ways doing IM in
SIP: one is page-mode using MESSAGE requests, which should take pretty
much the same route as INVITE (that is: authorization of caller,
normalization of callee, lookup in location table, then t_relay to
callee); the other one is MSRP, which is actually an INVITE with a
special payload. If you use sylkserver, then you can just forward the
INVITE to sylkserver, which has an MSRP relay integrated, otherwise you
can use http://kamailio.org/docs/modules/3.3.x/modules/msrp.html to
handle MSRP directly within kamailio without a 3rd party server.
