Virtual Extension is a feature that is unique to business VoIP solutions. A virtual extension, also called a virtual number, is a phone number that forwards to another phone number. The virtual number is not associated with any specific desk, and most often forwards to a cell phone. If the person who is being called at the virtual extension cannot be reached, the virtual extension has its own voice mail, which is separate from the user’s home/cell voice mail.
In effect, the virtual extension is like the “find me/follow me” feature, only it is set to go to the second number first. Virtual extensions allow all the employees to be part of the same phone system, even as they use their own phones to receive important work calls. The virtual extension is a powerful tool for small businesses.
