MetaSwitch and One Communications Pass Next-Gen Milestone

Market Wire, February, 2008

MetaSwitch announced today at the CompTel Plus show that its partnership with One Communications, a leading regional Competitive Local Exchange Carrier (CLEC), has reached a major milestone by successfully transitioning several key markets from a legacy voice infrastructure to MetaSwitch's next-generation voice service platforms. The migration has already enabled the carrier to realize significant operational cost savings in terms of power consumption and other efficiencies and is expected to produce a return on investment in less than 15 months.

"Our partnership with MetaSwitch was a key component in how quickly and smoothly this transition has gone," said Russ Oliver, senior vice president of strategy for One Communications. "The commitment of their entire organization, from the sales team to its highly skilled professional services organization, has provided real value at every interaction."

MetaSwitch's softswitch platforms provide the fundamental core of One Communications' new network infrastructure, providing a flexible, IMS-enabled platform to support innovative voice services today as well as set the stage for future communication service programs. The migration, which is happening in phases but will ultimately expand to include the entire network, has been completed in Appleton, Green Bay and Madison, all in Wisconsin.

One Communications had already deployed MetaSwitch's softswitch platforms network wide and implemented a "cap and grow" program for new lines of service. The decision to remove legacy Class 5 switches from service was made when One Communications launched an aggressive service creation and roll-out strategy that the legacy hardware could not support.

"One Communications' successful network migration demonstrates the highest level of commitment to its customers and is a clear indication of its intent to be at the forefront of service innovation," said Graeme MacArthur, MetaSwitch's chief executive officer. "To support their strategy, our commitment to One Communications was that we'd help them through each step in this migration, providing the vital support and services they required to realize their operational, service and business objectives."
