VoIP service providers fall into two categories. One is the bulk service provider that serves the wholesale segment. The second is the retail service provider serving end users such as enterprises. There is yet another category made up of end users and retail users such as internet cafes served by the second or the first category. Carriers and service providers realize the importance of providing such services due to the inherent advantages. They have the option of installing a packaged solution that works right out of the box and saves time. However, such solutions are usually expensive and the user is restricted by way of features available. A tailored VoIP Softswitch software solution is better in several ways.
