Abstract

A method facilitates providing private exchange functionality to a subscriber that is remote from the private network. In the private network, telephones connected thereto can be accessed via extension dialing. The remote subscriber can dial the extension of a second telephone connected to said private network. A local exchange receives the extension and translates it into a phone number for the second telephone. The local exchange then uses the phone number to establish a connection between the subscriber and the second telephone. The same method can be used to implement remote speed dialing and automatic callback through the private network.
