CenturyLink takes the VoIP network plunge with Sonus

CenturyLink (NYSE: CTL) has decided that the more efficient foundation for its voice traffic would be a converged IP network that could accommodate both legacy TDM and IP voice traffic across its fiber backbone. To reach that goal, CenturyLink turned to Sonus Networks (Nasdaq: SONS) and its suite of media gateways (GSX9000), policy management (PSX Call Routing and Policy Server) and its session border controller (NBS-9000).

In just four months, the service provider has completed the first phase of its IP voice infrastructure deployment, which will be built out in 22 U.S. cities. Needing to support seven million voice lines from two networks--the former EMBARQ and the former CenturyTel--without any disruptions, the new network deployment gives CenturyLink centralized management of its IP voice traffic.  

Along with accommodating its own voice traffic, Sonus' Network Border Switch will enable CenturyLink to more effectively interconnect with other service providers and create a foundation for new services, including media transcoding.

"We expect to achieve cost savings and efficiency gains from our new IP core network as well as from the ability to centrally manage our voice traffic across our fiber backbone," said Matt Beal, chief technology officer at CenturyLink in a release. "It will also enable us to provide more advanced services to meet our customers' future needs."
