This is perhaps the simplest of all methods of getting into the VoIP business. Wholesale calling card systems let you purchase calling card services from a VoIP provider, and resell them. Using this model, it is usually very easy to apply your own brand to the calling card. The best way to go about this is to make use of a fully-featured wholesale calling card platform, which eliminates the need to run your own equipment or infrastructure, allows you to create your own rate table, and allows you to create your own brand for resale.
