Westford, MA., and Las Vegas, NV., April 02, 2008 – Sonus Networks, Inc. (Nasdaq: SONS), the market leader in IP communications infrastructure, is helping mobile operators to embrace flat rate pricing plans without the major increases to operating costs usually associated with increased traffic or subscribers. The core infrastructure components offered by Sonus can be integrated to enable operators to retain competitive pricing models through IP-to-IP peering, advanced media services and transcoder-free operation. Sonus Networks is exhibiting these and other wireless solutions at CTIA 2008, Las Vegas, at Booth #3439.

Consumer demand is pushing wireless operators to deliver flat-rate pricing, both in the U.S. and across Europe. To remain competitive in a market with downward price pressure, operators face the challenge of reducing and controlling network infrastructure costs. Flat-rate plans will inevitably lead to an increase in call volume, which will become costly for carriers who are required to deliver increasing traffic volume to complete calls outside of their wireless network.
