CenturyLink, Sonus Networks deploy voice over IP network

To incorporate both legacy TDM and IP voice traffic on the same infrastructure

By CBR Staff Writer

Sonus Networks, a provider of network transformation through IP communications technology, and CenturyLink said that they have completed the phase one implementation of CenturyLink’s IP voice infrastructure. The migration brings traffic from CenturyLink’s voice network into secure, easy to manage IP network.

The network includes the deployment of Sonus Networks media gateways, policy management and session border control offerings in 22 cities across the US. It enables CenturyLink to leverage its fibre backbone to incorporate both legacy TDM and IP voice traffic on the same infrastructure and allows for cost saving and provides centralised management of the IP voice traffic, the companies said.

The companies said that the key part of the new network is the addition of a Sonus Network Border Switch for secure IP-peering, session control and media management. The Sonus Network Border Switch provides CenturyLink with a secure and cost effective means of interconnecting with other service providers and also offers the opportunity to add future services including media transcoding.

In this project CenturyLink, working with Sonus Global Services has deployed the Sonus GSX9000 Media Gateway, the Sonus PSX Call Routing and Policy Server, the Sonus Insight Element Management System and the Sonus Network Border Switch (NBS-9000) for enhanced border security and advanced IP peering capabilities, the company said.

Mohammed Shanableh, vice president of worldwide sales at Sonus Networks, said: “CenturyLink has very demanding standards for its voice network. I am pleased that the Sonus Global Services team worked seamlessly with the team at CenturyLink to meet the aggressive deployment schedule successfully. This Sonus deployment will enable CenturyLink to grow their network to meet the needs of its expanding customer base.”
