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
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

That sounds like a typical NAT problem. 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?
