Hi Daniel,

Thanks for your answer. My question was more related to why kamailio opens those extra sockets also when it's not sending any data. Is that the normal behavior?

You are right, i will read netstat's manual for how long and why keeps those sockets opened.

Thanks again!

Diego

Hello,

I am not sure what ESTABLISHED is meant by netstat for UDP sockets, because there is no connection defined for UDP (datagram socket is kind of shoot and forget) -- maybe it track that there was some traffic and remembers that for a while. Perhaps reading the manual of netstat will help to understand better.

Cheers,
Daniel

Hi Guys,

We have two network interfaces. One public and one private. We had enabled mhomed and works great BUT if we do a netstat -naup | grep 5060 we see that some sockets keeps opened also when the call is finished. The source port in netstat it's not 5060 so I suppose that kamailio use another one for something else.

Is this the right behavior? How long does this sockets remain opened? Are we missing something in our cfg?
