SIP-Based Clients


Protocol clients capable of communicating with Communications Server directly over SIP are referred to as SIP-based clients, because they support a native SIP stack. Such protocol clients offer a SIP stack that is interoperable with the SIP and media extensions of Communications Server. Examples of SIP-based clients are software-based protocol clients such as Office Communicator, and SIP-based phones such as Office Communicator Phone Edition and Office Communicator Mobile.
