Abstract: Disclosed embodiments relate to a shared computing system for use in telecommunications between end-point telecommunication devices comprising a plurality of instances of a telecommunications service component and a version control gateway configured to route a communication connection from an end-point telecommunication device to an appropriate instance, of the plurality of instances, of the service component. In some embodiments, different end-point telecommunication devices may use different instances of the service component. Some embodiments relate to a network for telecommunications between end-point telecommunication devices, a version control gateway for use in the system of the disclosure, a method of providing a telecommunications service to a user, a method of migrating a user from one software version of a telecommunications service to another, and computer programs and computer-readable media.

Abstract: A telecommunication network 30 for telecommunications between telecommunication end point devices 36,37,38, such as telephones or video phones, the telecommunication network 30 comprising a plurality of telecommunication device control systems 40 implemented by a computer system. Each telecommunication device control system 40 is shared by telecommunication end point devices 36,37,38 allocated to it and is configured to control communication connections involving telecommunications originating from telecommunication end point devices 36,37,38 allocated to it and other telecommunication end point devices. At least some functionality of the plurality of telecommunication device control systems 40 is shared by at least some parts of the computer system.
