VoIP's Neutral Tandem Uses Sonus Networks Products

More and more carriers worldwide reportedly are moving away from existing TDM interconnections and adopting SIP interconnections as a preferred interface method, industry insiders say.

This week, according to Sonus Networks – a Massachusetts-based provider of IP communications infrastructure – Neutral Tandem, a provider of tandem services to wireless, wireline, cable telephony and VoIP providers, says it has replaced its nine TDM circuit switches with IP-compatible switches and is in the final phase of its network transformation.
Neutral Tandem (News - Alert), which offers inter-carrier communications across the United States, said that it encountered increased billable traffic by five times since 2005, so it decided to go all IP in 2006. Now, it has deployed Sonus’ IP switching technology, in order to serve 100 markets across the United States.
Neutral Tandem’s officials said that the new transformation has reduced operating costs, enhanced the levels of service that company offers to its customers as well as enabled it to introduce new services to the customers across the United States. The company is now able to carry more than six billion minutes of IP voice traffic a month and serves 100 markets in the United States.
“We have invested in the technology and architecture of the future to serve our customers’ needs as their managed tandem provider of choice,” said Surendra Saboo (News - Alert), chief operating officer of Neutral Tandem. “We could not compromise on service or availability, so we selected Sonus to transform our network. The robust, carrier-grade network running today offers the scalability, security and flexibility that our customers demand.”
As part of transformation process, Neutral Tandem has deployed a complete suite of Sonus’ IMS (IP Multimedia Subsystem)-ready solutions, including the GSX9000 open services switch, the PSX Policy Server, and the Sonus Insight Management System.
Sonus said that its comprehensive IP Multimedia Subsystem (News - Alert) solution addresses the complete range of carrier applications, including residential and business voice services, wireless voice and multimedia, trunking and tandem switching, carrier interconnection and enhanced services. Company’s voice infrastructure solutions are deployed in service provider networks.
Additionally, Neutral Tandem has also deployed the Sonus Network Border Switching – for enhanced security as well as direct IP-to-IP peering capabilities.
