摘要： One object of the invention is therefore to provide complete integration of the remote extension of an exchange so that the mobile phone user can use all end-user features and services, like for example call-back and conference. A remote call coming in as a trunk call can be looped through the invented communication platform, the exchange, such that it is perceived as an internal incoming call. The invention provides a telephone exchange that comprises means for said telephone communication devices as extensions, and means for storing unique identities of said telephone communication devices.
