[SR-Users] Kamailio not processing SIP TCP

[Daniel-Constantin Mierla]

Hello,

is it this about a sipcature node? If yes, then it receives the packets
over HEP, meaning that is not going to the normal processing path.
Kamailio detects it is not a SIP packet, executes some callbacks for
non-sip packets registered by modules (in this case sipcapture). The
module detecting it's a packet for it, can execute the request_route
once it builds a local sip packet.

To troubleshoot further, run with debug=3 in kamailio.cfg and see what
you get in the logs.

Cheers,
Daniel
