PBX System

Yeastar PBX System

The primary function of a PBX is to route incoming calls to the appropriate extension within the office and to share a group of phone or “trunk” lines between extensions. When an outside call is required, an access number is dialed (example “0”) to access an outside trunk line. The PBX then transfers the call to the phone company’s Central Office. The telephone company then forwards the call to the desired number in the outside world.
