It all depends on where you're calling. I prefer companies that are pure SIP service providers without any proprietary stuff.
Research the rates for your destinations and sign up for one or more services that suit your needs. For example voipcheap has a decent deal where you get free calls for 90 days to most European countries after you deposit 10 Euros in your account.
