Evolution of Cloud PBX VOIP

We are living in the age of the computers and we no longer do things the traditional ways.  Businesses – regardless of their size and scale of operations – are becoming increasingly reliant on the Internet for its day-to-day operations.

As many of us are aware, PBX (Private Branch Exchange) makes connections among the internal telephones of a private organization and also connects them to the PSTN (Public Switched Telephone Network) via trunk lines. They not only facilitate telephone communication but also fax messaging and modems for all other voice/data transmissions.

Having traditional PBX was expensive because it required the buying of the actual PBX equipment and the concomitant installation, operation, and maintenance fees. The installation of the equipment entailed occupation of floor area.

These considerations led to the emergence of hosted PBX. In a hosted arrangement, the PBX is located at and managed by the telephone service provider, and features and calls are delivered via the Internet. The user just signs up for a service, instead of buying and maintaining expensive hardware.

One of the latest trends in PBX development is the VoIP PBX, also known as an IP-PBX or IPBX, which uses the Internet Protocol to carry calls.
