Any recommendations for an EU VOIP provider that we can port our US phone numbers to?

Our current US provider is garbage. (We maintain our US phone numbers to make a few expat things easier.)

@jeffwatkins The one I've settled on is Dingtone. It has all the features, but it's no Skype. Then again, Skype hasn't been decent since MS redesigned it and shut it down.
@seanreilly I'll give them a look. They can't be worse than Voiply.
