Abstract: A network entity comprises an interworking function. The network entity is between an endpoint and a registrar in a telecommunications network. A message is received for the registrar from the endpoint, the message comprising data identifying an endpoint characteristic of the endpoint. A message is received for the endpoint. A processing action to be used to process the received message for the endpoint is determined based on the data identifying the endpoint characteristic of the endpoint comprised in the received message for the registrar from the endpoint. The received message for the endpoint is processed in accordance with the determined processing action.

Abstract: Embodiments of the invention provide methods and apparatus for providing one-telephone dialing number telephony services where only a single telephone dialing number is required for each subscriber, despite each subscriber having multiple telephony devices on which they wish to be contacted. Calls to a one-telephone dialing number telephony service subscriber may be detected at a telephone switch using one or more triggers configured in association with a device-shared telephone dialing number allocated to the subscriber. Upon receipt of a call connection request to a subscriber, control of the call is assumed, for example by redirecting the call to a service platform capable of generating multiple call connection requests. Multiple outgoing call connection requests are transmitted to multiple telephony devices, including a mobile telephone, associated with the device-shared telephone dialing number allocated to a subscriber.
