The ShoreTel system is a fully distributed IP
phone system with no single point of failure. Call control is
distributed to intelligent gateways - called voice switches - and
voice applications, including voicemail and automated attendant, run
on standard server hardware from anywhere on your IP network. The
result is a single-image system across all geographies, with
complete feature transparency. The days of multiple PBXs, voice mail
systems, automated attendants, and ACD systems are over. With
ShoreTel, the phone system is distributed, the voice applications
are integrated, and the management interface is best in class.
