Hi Benny! Thanks for the tip! It works now!! I've got F-secure firewall on this computer. I changed the trusted network adapter from "none" to the one that I'm using and it worked like a charm. This is maybe not the safest way of doing it so I tried to apply a rule and also add a so called "service" in F-secure's lists but without any difference than before. So instead I activated the "application control" and got those irritating popups, saying a program wants to access internet. I accepted it for my SIP UAs, and it worked again. Another question about the same topic: Is it possible to activate the keep-alive routine for UDP without STUN enabled?

Strange as it might sound, I've sometimes got the same problem, not with SIP though but with our TURN client. After 1-3 minutes idle the data sent by TURN server (located on the same LAN!) can't reach the client, and it will only get through again after client sends outgoing data to to TURN server. Wireshark says data does arrive in client, but still the client application doesn't read it. I also tried that on a WinXP SP2. And this problem goes away once I turn off my Windows firewall. Could you try that?
