Hello,

the logs on tcp are mostly about the remote closing the connection. So nothing wrong about tcp reported by kamailio.

Maybe you can look at the tcp connections details via rpc commands and see if you can spot a reason there:
 - http://www.kamailio.org/docs/docbooks/devel/rpc_list/rpc_list.html#core.tcp_info

You can run them via kamcmd.

Cheers,
Daniel

And maybe other TCP params that I have in the kamailio config :

 

# life time of TCP connection when there is no traffic

# - a bit higher than registration expires to cope with UA behind NAT

tcp_connection_lifetime=3620

tcp_connect_timeout=1

tcp_keepcnt = 10

 

tcp_keepidle = 10

 

tcp_send_timeout=3

regarding error , yes  I have a lot of error regarding SDP and a few regarding TCP.

 

for the SDP , initially I have think that  I call rtpproxy_offer / rtpproxy_answer for a request that don’t have any SDP but all rtpproxy method have a check with has_body("application/sdp")
