Solution for Service Provider
Equipment that makes connections among the internal telephones of a private organization(usually a business) and also connects them to the public switched telephone network(PSTN) via trunk lines is called Private Branch Exchange(PBX). Some PBXs in SMEs which involve from 10 to 50 workers are occasionally called Key System or Key Phone System for their additional service keys other than number keys.

For quite some time, telcos have provided PBX functions through so called Centrex Service from telephone offices.
From customer's point of view in reality, Centrex Service takes relatively greater expense on overall maintenance, for it provides PBX functions to customers without installing PBXs in their offices but they still have to pay regularly for additional lines and services. This reality has affected some enterprises to consider their various environments and situations and then to use Centrex Service, but it also has affected most of other enterprises to install and own PBXs by themselves. With this kind of voice communication service which has lasted for tens of years, and recently added with IP technologies, the competition among voice communication service providers to have control over enterprise market is already getting more and more serious.
From service provider's point of view, the first priority is to increase and secure number of subscribers and to decrease cost of inducing new subscribers. How can the goal be achieved?
