Spark Selects Metaswitch Virtual IMS Core for VoLTE Proof-of-Concept

Metaswitch's Advanced Consumer Communications Portfolio Helps Network Operator Along the Path to a Unified IP Network and Quicker, More Agile Product Development

LONDON, UNITED KINGDOM--(Marketwired - June 22, 2015) - Metaswitch Networks, the world's leading network software provider, today announced that Spark New Zealand has deployed Metaswitch's Clearwater virtualized IP Multimedia Subsystem (vIMS) and its virtualized Perimeta session border controller (vSBC) as part of a virtualized voice over LTE (VoLTE) proof-of-concept, successfully using the deployment to make high-definition voice calls to a wide variety of mobile devices.

Part of Spark's transformation involves unifying its mobile and fixed networks into a single, flexible, IP-based network that enables it to provide services to customers on any device they choose. Metaswitch's Clearwater IMS core provides a foundation for complete wireline and wireless IP communications while removing the typical cost barriers to deploying IMS-centric VoLTE.

"Mobile technology is constantly changing, and our network needs to handle not just what is possible today, but what our customers will demand in the future," said Spark COO David Havercroft. "We took this project from a concept on paper to a functioning demonstration in less than 14 weeks. We're not letting up on this pace of innovation and change to deliver value to our customers."

"Metaswitch is pleased to be part of Spark's rapid movement towards a more flexible, all-IP network," said Ray Tseng, VP of APAC sales for Metaswitch. "With the Metaswitch Consumer Communications Solution, network operators like Spark are able to drive down network costs, reduce the need for legacy infrastructure, and take advantage of today's increasingly powerful mobile devices to provide exciting new services to their customers."

Spark New Zealand provides data and voice services to more than 2.1 million mobile devices and delivers more than 674,000 broadband connections across New Zealand.

For this project, Spark partnered with Cisco Systems for its virtualized network infrastructure, management, and packet core functions; and OpenCloud for the Application Server functions. For more, please read Spark's press release:
