VIP Call

VIPCall helps enterprises address this imbalance in the system. Traditional caller ID systems were static i.e. it wasn't easy to change the number that shows up on the recipient's phone. VIPCall allows users to customize this piece of data. So, you can show one number for call 1 and another for call 2 etc.
VoIP service providers can set up this feature in different ways. Some vendors allow users to switch between multiple numbers within their account. Others need you to provide a list of numbers that have this feature enabled. In some systems, you can dial a specific code to change the number displayed on outbound calls. While you do have to memorize the codes, it is an easy way to switch caller ID for multiple calls.
