What Does Virtual Private Branch Exchange (VPBX) Mean?
A virtual private branch exchange (VPBX) is a business phone system that provides call routing, follow-me calling, voice mail, fax and automatic call distributor queues delivered over the public-switched telephone system.
VPBX offers a communication solution optimized to address the requirements of dynamic businesses using the latest IP technology. Unlike a traditional private branch exchange (PBX), businesses do not need to purchase or install special equipment because VPBX is run through software.
Virtual private branch exchange is also known as Centrex.
