[edit intro]

This article is about Convergence of communications. For other uses of the term  Convergence , please see Convergence (disambiguation).

Convergence of communications, in varying and unfortunately not yet standard phrasings, is the goal of having all types of human-to-computer and computer-to-computer communications converge onto (i.e., all run over) a common infrastructure using Internet Protocol version 4 or Internet Protocol version 6.

It is neither necessary, nor desirable from a security standpoint, that they all run over the public Internet. All of these services can be restricted to other than the Internet, such as intranets or extranets.

This definition of convergence does not attempt to standardize the applications themselves. Instead, it includes the technologies that enable application-specific communications to be transmitted over standard interfaces to information delivery systems using Internet Protocol, Session Initiation Protocol, and similar protocols and interfaces.[1]

Converged services may use custom software (e.g., private branch exchange) on a purpose-built router, or a general-purpose computer.
