NEC PBX Systems info

NEC's UNIVERGE™ NEAX® family of voice systems has been designed for a lifeline rather than a lifecycle.
For nearly two decades, each successive model has migrated to the next, allowing new technology to be adopted when it is practical for the end user.
Relatively simple upgrades have kept the UNIVERGE NEAX voice systems current in technology and functionality, all while preserving up to 80% or more of the customer's existing investment.
