i have been wondering why kamailio refuses to forward bye to $du
sip:192.26.99.39:8000;transport=tcp;lr;ftag=a8266461a81c723o0
wireshark shows that it is not even trying to set up tcp connection to
the destination and with telnet i can verify that tcp connection can be
set up.
debug at level 3 is below.
