Newbie just got a Nokia N800 yesterday, updated to OS2008 immediately.
Now, how can I make the VOIP SIP work? I'm in US and using viaTalk VOIP, viaTalk supports SoftPhone like Xten, and provides only the following parameters for generic SIP setting:

Display Name; User name; Password and Proxy Server.

In the OS2008 SIP account settings, how can I make it work? I entered the Proxy Server in the box after the "@"... it never been able to connect.
