Swedish cable broadband operator Com Hem has selected Nokia Siemens Networks to provide it with an IP Multimedia Subsystem (IMS) in order to enhance its VoIP telephony services. The IMS network architecture is designed to enables richer IP-based communications. Under the agreement, Nokia Siemens Networks will supply and integrate a complete IMS ‘core solution’, including an ENUM server for translating telephone numbers into IP addresses for use by internet users, and other functionality to enhance Com Hem’s existing VoIP service based on the Siemens SURPASS hiQ VoIP application server. According to a press release, IMS will allow Com Hem to: optimise the use of its existing network infrastructure to meet the rapid growth of its customer base; develop and quickly introduce new voice and data services; enter new partnerships with more telecom operators; and reduce operating costs. ‘This is a strategic move that will not only provide our customers with the best VoIP offering on the market, but also open the way to new applications and converging services,’ said Martin Kull, CTO of Com Hem.
