A server that can be segmented into many virtual servers or virtual machines (VM). A VM operates exactly like a dedicated server, but sits on a larger secure shared machine.
There are two categories of Voice over Internet Protocol (VoIP) service providers: one uses the public Internet to transport calls and is known as Internet Telephony. The second category routes voice calls over private IP networks. This enables the service provider to manage the call from end to end, ensuring voice quality and allowing the carrier to provide service level agreements (SLAs).
