Hello Andrey,

before going into your cfg, lets have a look to some easier to verify topics:

Are the TCP SIP messages actually received from Kamailio? You can verify this e.g. by 
looking to the network traffic with tcpdump and friends. Or you can enable debug logging 
in the cfg and will see the packet processing in the core and parser. 

With the enabled debug logging you should also get more hints about the actual flow in the 
configuration, maybe this gives you some hints about the error.

Best regards,
