Telephone communication

摘要

A telephone connection is established between a first terminal and a second terminal. The first terminal is presumed to be associated with a subscription in a first home telephone network in which the terminal is identified by a first network identity. Correspondingly, the second terminal is presumed to be associated with a subscription in a second home telephone network in which the second terminal is identified by a second network identity. A host resource routes a call from the first terminal to the second terminal based on a combination of the first network identity and a first common telephone number in the first home telephone network dialed by the first terminal. The first common telephone number is selected such that it is unique and is adapted to be shared among a group of users in the first home telephone network.
