Reasons Why PBX Phone System Setup is the Right Choice

Posted by arun on May 22nd, 2014

PBX i.e. Private Branch Exchange is a call routing system wherein a centralized “exchange” received the outbound calls and transfers to the respective extension numbers or enables the extension numbers to dial and get connected to the external telephone numbers. When this routing is done in an automatic manner, the PBX becomes PABX. The PBX will resemble a normal public telephone exchange, but in the miniature form. The difference is that in the public system one to one call alone can be made. In PBX, the call received can be diverted to different departments i.e. different extensions. The stand alone telephones in an organization may be integrated through the PBX, without anything, including the wiring being changed.

Functionally, the main call processing duties PBX Phone System are establishment (mapping) of connections (circuits) between two users, maintaining such connections, disconnecting the same when the user does not require and metering of the calls and other statistics. For these, PBX requires some interfaces for connecting the extensions to the exchange, the PBX to each other, the PBX to trunk lines and for gathering CDR (call detail record) and SMDR (Station Messaging Detailed Record).

Besides the above basic functions, the PBX Phone System setup comprises of many calling features/capabilities, enabling you to enjoy all the advantages of sophisticated communication. In general, they include auto attendant, automated directory services, busy override, automated greetings or welcome messages or caller tunes for the incoming calls, call blocking, call forwarding, direct inward dialing, speed dialing, teleconferencing, connections to the voice mail, etc.

In view of the telecommunication technologies, witnessing lots of advancements, the legacy PBX Phone System (containing hardware and analog telephone network) also gets advanced, in that getting upgraded to IPPBX system. IPPBX refers to a digital system of PBX, which will handle VoIP calls. Further, these IPPBX systems will also be cheaper to own, simpler to maintain, besides having a plethora of features, required for modern communication management, practically at no extra cost.

A disadvantage with the legacy PBX Phone System setup is that you cannot use it for IP telephone, without proper adaptation for IP. Further, when you install VoIP also, you are depending on another service provided i.e. for broadband. When you use just land lines, the connectivity is ensured through a copper wire circuit directly to the switching network of the telephone service provider. For some companies, the cost of calls with VoIP tends to be more.
