It seems that you have fork set to no, Let kamailio fork and collect logs via syslog (not via stderror).

When I start Kamailio, I see the following in the output to stderr:

Listening on

         udp: 172.16.0.57:5060

         tcp: 172.16.0.57:5060

Aliases:

         tcp: VRTPENGINE:5060

         udp: VRTPENGINE:5060

WARNING: no fork mode

0(6299) INFO: <core> [core/tcp_main.c:5042]: init_tcp(): using epoll_lt as the io watch method (auto detected)

Here’s the problem:

When I connect via UDP, everything works fine. I can connect and see all SIP traffic.

However, if I try to connect via TCP, I see the initial SYN packet in attempting to establish a connection.

Kamailio responds with an [RST,ACK] message and the TCP connection is never established. No further TCP traffic is sent.

Any ideas on what I’m doing wrong?
