Hi Mykyta,
since you are plain sip without encryption you can see your
sip-traffic on the wire,
use sngrep on the kamailio box to figure out whats with the
sip-dialogs - it helps a lot.

and if its more an kamailio config problem, it would be better to stay
at sr-users@.
Or you can setup an webhomer for debugging.
Kind Regards

Once a call is answered FreeSWITCH sends a 200 OK SIP message to
your Kamailio loadbalancer. As per the SIP spec your kamailio box
should respond to a 200 OK with an ACK. The FS logs show that it
never receives an ACK, and it repeatedly tries sending the 200 OK
with no response. After 30 seconds without an ACK FS will assume
the call has failed and hangup.
Looking at your Kamailio SIP logs you can see the 200 OKs getting
through okay, and no attempt to send an ACK back to FS. I think
this indicates an issue with your kamailio.cfg rather than FreeSWITCH.
