First of all, add some log or xlog statements to your config and check /var/log/messages to see where the INVITE ends up in your config (add at least a log line at the beginning). SER probably kicks at something in the config. Also, make sure that you get ALL port 5060 traffic, both incoming and outgoing.
At first glance I don't see anything wrong with your ser.cfg, so I need more info.

It's strange, but I do see the SIP INVITE messages being sent in the
ethereal log. Why they don't reach to the server? SER is connected
directly to the internet, without any NAT. On the other hand, REGISTER
messages do get to SER and the client recieves the 200 OK and all
intermediate replies as well.

I have attached the clientside ethereal log for you to see.

I am lost.
