Pingo is a typical prepaid calling service that uses VoIP to provide inexpensive calling to their customers. While this works great for individuals, this doesn't work quite as well for businesses who need to have central control over their users.

Pingo now offers a business service called Pingo Business. You get the same cost savings and employees get calling card convenience, but the business gets the centralized control.

Pingo will give business $10 in free calls just to try out the service. They will go over your international calling bills with you and show you where you can save money.
