Yes, to me it looks like a firewall issiue, as the log shows received ip address.

So check if the port 5060 is open for TCP traffic, just not sure why the connection try is not in the log……..

Success.

Sorry, this test was done on a public server that's why it was showing public IPs. I was trying out opensips and kamailio and same response for both. Do you think this is a network firewall issue?

But as I am not a guru at all and this is a Kamailio users mailing list and not an opensips list….

I just googled the error, found that for Opensips and Kamailio it has something to do with not being able to make a tcp connection.

So, check the port translations, make a tcpdump of wireshark dump and see if what is going wrong.

You said that the clients and Kamailio were on the same lan, but from the logging you can see that you are on the internet…….

Hope this helps a bit.

Good luck.

Hello Jason,

What you should do is on the Kamailio server do an ngrep, that information will make it possible for the people on the list to take a look and help you.

By only telling your experiences it is hard to help you.

Just give the command: ngrep –qt –W byline port 5060 and then do the test calls, so from android to xlite and vice versa.

Save the info and paste it in the case.

Good luck.

Gertjan

Subject: [SR-Users] kamailio call problem

Hi,

I installed kamailio v 3.1.6 rpm. I used the default configuration. Kamailio started. I have two clients one is an android phone using native sip client, and the other one x-lite. I can call x-lite to phone but not the other way around. When I restarted kamailio, I can call phone to x-lite but not the other way around. The first one I did when I restart kamailio will be the only leg that will be working, then I have to restart again if I want to do the reverse. Has anyone encountered this problem? How do I fix it? I'm on a LAN, kamailio server and the two clients are on the same LAN.

Thanks,
Jason
