Following the tutorial http://pipip.de/index.php?section=other&sub=nokia_vpn I managed it to get access to my universitys VPN with my N80. Browsing works nicely. But the VOIP calling seems to be not working. I set up a new access point with VPN, which is working nicely for the browser. Then I specified it even as the default internet connection in my profile; but the VPN access point doesn't show up, when I want to register to the service. Only the WLAN network alone appears as access point. What do I have to configure in order to use VOIP over VPN?
