Sonus Networks has entered into a distributor agreement with NextGen to offer and support the full portfolio of Sonus Networks' carrier-grade IP communications solutions to the Japanese market. The relationship has already proven successful with a major Japanese carrier choosing NextGen to undertake the nationwide deployment of its IP trunking and switching network. Using a Sonus IMS-based next generation network, this deployment will include the Sonus GSX 9000 media gateway, the Sonus PSX centralized routing and policy management server and the Sonus SGX signaling gateway.

The contract was awarded following a series of rigorous evaluations by the carrier, which included solutions from local and global IP network vendors. The Japanese carrier stated that it was the proven robustness, reliability and scalability of the Sonus solutions, combined with the SIP/VoIP implementation expertise of NextGen that led to the contract being given to NextGen with Sonus Networks.

With the distributor agreement with Sonus Networks and the construction of the large-scale system using Sonus solutions, NextGen plans to further enhance its SIP/VoIP portfolio and to continue providing solutions that meet demanding needs in the carrier market.
