Making the case for IP PBX Systems

The small-to-medium business communications market is changing considerably because of major ongoing development in core networking technology. Voice communications have been migrating from time-based to packet-based switching. An IP PBX is likely to be the standard design platform of the future for enterprise communications systems. The benefits to customers who select an IP PBX exceed the drawbacks.

Performance Value of an IP PBX:
Converged network
Packet-switched LANs today carry telephone-generated voice communications in addition to computer system data traffic. From the perspective of a data communications network designer, the telephone is viewed as just another client, and voice features and functions are just other applications supported by a LAN-based server. LAN bandwidth capacity continues to increase. This means more point-to-point video communications traffic will be carried between desktops, and there is a decreasing dependence on larger, more expensive, room-based videoconferencing systems.

University of the transport protocol
Internet Protocol (IP) control and transmission is the standard for data communications networks. The concept of a LAN and WAN is a fact of network operation across all industry sectors. The client-server communication model is a dominant mechanism. For a customer searching for an IP PBX system solution, the current data networking infrastructure is favorable.

Network bandwidth
Now that IP has become the transport mechanism to carry both voice and data, using the same communications network for both traffic types reduces overall bandwidth requirements. The two traffic streams could be interleaved, and QoS levels can be engineered and programmed to satisfy real-time voice communications requirements. As customers migrate from circuit-switched to packet-switched communications, there will be cost savings and increased network efficiency from economies of scale. Cost savings are attributed to off-premises communications because PSTN trunk carrier facility requirements are reduced with the introduction of IP.
