Abstract:
1. A system for establishing a telephone connection between a first terminal and a second terminal, the first terminal being associated with a subscription in a first home telephone network in which the first terminal is identified by means of a first network identity, and the second terminal being associated with a subscription in a second home telephone network in which the second terminal is identified by means of a second network identity, characterized in that the system comprises: a host resource comprising one or more memory storage areas and one or more processors, adapted to, with the one or more processors, route a call from the first terminal to the second terminal based on a first unique 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 being adapted to be shared among a first group of users in the first home telephone network, wherein the first unique combination of the first common telephone number and the first network identity is established by: receiving an initial dialing instruction from the second terminal, the initial dialing instruction containing data uniquely identifying the first terminal, receiving user data specifying the second network identity, deriving the first network identity based on the initial dialing instruction, allocating the first common telephone number based on the first and second network identities and any first common telephone numbers previously allocated to the first terminal and/or the second terminal in such a manner that a combination of the first network identity, the first common telephone number and the second network identity becomes unique, storing an entry representing the first unique combination, and sending a service invitation message to the first terminal, the service invitation message including data specifying an identity of the second terminal and the first common telephone number, wherein the allocation of the first common telephone number comprises: a first interface node connecting the first home telephone network to at least one interconnecting network, and a second interface node connecting the second home telephone network to at least one of the at least one interconnecting network, wherein at least one of the at least one interconnecting network is represented by a packet switched network, and each of the a first and second interface nodes is adapted to handle telephone traffic over packet switched networks.
