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?
