Yes i have tried that but all the necessary ports are closed on the router i'm behind.
Logging in to this VSP to place calls isn't a problem so it looks like my credentials are ok.
Tonight i tried again, i deleted my previous attempt and entered the account settings.
At first i got the Auth Sent message but then it changed to a "-" (like you get when setting up an un-registered VSP).
Receiving calls still isn't possible...
