Abstract

See full text

A call-routing method for a virtual private network consisting of two or more private communication units which are interconnected via switched connections of a public network as required, wherein to switch the switched connections, a service is dialled which then initiates further switching based on a private numbering plan, characterized in that to establish a connection to a subscriber of the private network, a subscriber of the public network dials the same service which then initiates further switching to one of the private communication units, that the service assigns tariffing attributes to each call initiated by it, and that the service assigns to a call between the private communication units other tariffing attributes than to the other calls. It is also directed to a service computer that supports switching calls both within and outside a private network, with different tariffing attributes assigned to the different type of calls. The service computer switches both calls between private branch exchanges of a private network and calls from outside with the aid of a private numbering plan, the latter being initiated with a different tariff. It is also directed to an exchange having at least one such service computer.
