The concept of "roaming" is extended to wireline networks with a network hosted technique which emulates a wireline telecommunications network user's environment when the user is using a wireline telecommunications device located at a physical location other than his or her "home" location, or when using a wireline or wireless telecommunications device other than his or her own regardless of the location. Any telephone or other telecommunications device being used by the user advantageously appears to be logically connected directly to his or her home telecommunications network, irrespective of the location of the telephone or other telecommunications device being used and the telecommunications network to which that device is actually connected.
