[SR-Users] Kamailio TCP Problems

Looking for some help with a TCP issue in Kamailio.
I am running load testing through the proxy with a topology of UAC > Proxy
With UDP it works fine (using SIPp scripts) - when I turn to TCP as the
transport i get the following error in the kamailio logs:
ERROR: <core> [tcp_main.c:4159]: handle_tcpconn_ev(): connect
The IP address stated is the UAC which is sending an INVITE to the Proxy,
which seems to send back a 100 TRYING to the UAC which is followed by
repeated INVITE messages.
It looks like the leg from the Proxy to the UAS is never established using
TCP - however if I send the SIP messages to the Proxy via TCP and set the
UAS to receieve in UDP Kamailio completes with TCP > Kamailio > UDP.
When the UAC is set to send on TCP and UAS set to receive on TCP netstat
shows the ports as listening.
Can anyone please help?
