I have been a OneSuite customer for a few months, for a mix of long distance calls within the US and to some parts of Asia like China, Philippines and Japan. Line quality is often great and their prices are very good. Their reliability also improved from the first few tines I've used it. One feature I had found very helpful was their dedicated fax & voicemail line for $1/month called MessageOne. Onesuite Voip feature is also nice but I really haven't maximize it yet but tried it a few times and quality is close to using their regular phone card services.
