Come to think of it, I have premium routing turned on too and I have been trying to call the UK from Christmas day until today, and calls not going through - perpetually busy.
I will try another server and see if it gets resolved, else I will open a ticket.
The sad part is I thought my Uncle's phone was down, had me worried stiff until he called today. Never did I think the problem was my provider! You see VOIP.MS had been solid to the UK before now.
Now I have egg in my face over this post - the issue was mine. Because of some unknown calls on my other A/C, etc I had been proactive in restricting call features and had turned off international calling on the "Account Setting" --> "Account Restrictions" tab. This was my problem.
Re-enabled and I am making premium route calls again to the UK.
