IP-PBX Takes Digital Networking One Step Further

3Com White Paper

In 1998, 3Com introduced the NBX® solution, the first IP-PBX. The IP-PBX changed the fundamental structure of the PBX market to deliver a new set of benefits to enterprises. Since their introduction, 3Com has shipped more than 18,000 IP PBX phone systems and 650,000 IP PBX ports.

For the first time, new IP-PBX shipments exceed traditional PBX shipments. The trend represented by this shipment data can be traced to IP-PBX architecture that allows businesses to reduce infrastructure cost while improving productivity.
IP PBX - Offer

With an IP-PBX, the Local Area Network is the platform for connecting smart IP phones logically over a shared packet network to the call manager. This unifies the data applications and the voice network, but places demands on the packet prioritization aspects of the LAN infrastructure to ensure user satisfaction with the quality of audio. Power to the IP phone is provided via the standard power brick-style transformer or via Power over Ethernet using the IEEE 802.3af standard.

Easy configuration of IP-PBX services is aided by browser-enabled administration and moving an employee with an IP-PBX is as simple as unplugging a telephone and plugging it in at a new location—as opposed to costly service calls from legacy PBX vendors. Additionally, IP-PBX owners do not have two separate networks to manage or the costs of additional infrastructure.

Selecting the right IP-PBX is an extremely important business decision. Many products are marketed as IP-PBXs but actually offer traditional PBX architecture and IP phones. The capabilities of these systems may rely on traditional rather than IP switching, resulting in the need to purchase conventional handsets, hardware that requires two backplanes with two points of failure, and processing requirements that exceed those needed by an IP-only system. These solutions may fail to deliver economies resulting from IP benefits such as the reduced cost of moves, adds, and changes and the savings of wiring a single converged network.

IP-PBX technology is integral to the SIP-PBX, an important and emerging product category for IP telephony in enterprises. This category of product uses the Session Initiation Protocol (SIP) to establish connections between users, and combines the local features of the PBX with the networking advantages of the IP-PBX and the scalability and trunking services of the softswitch. The SIP-PBX delivers a new architecture for enterprise communications applications, enabling enterprise-wide features, find me/follow me support, and extensive presence management. The 3Com® VCX™ solution is the first entrant in this new category.

SIP-PBX Fulfills the Promise of VoIP for Enterprises—New, Advanced Applications

3Com White Paper

The SIP-PBX is a new category of product for enterprise-wide communications and communications-intensive applications.

It combines:
  • the locally-delivered services of the PBX
  • the IP networking features and distributed architecture of the IP-PBX
  • the trunk management (trunks interconnect two or more voice devices over the wide area network) power of the carrier softswitch

The SIP-PBX uses advanced protocols such as Session Initiation Protocol (SIP) to enable a new framework for advanced enterprise-wide productivity enhancing and customer interaction applications.

The SIP-PBX can be deployed in a variety of customer scenarios. The telephony networks of most major enterprises use a host of vendor equipment that has delivered digital voice services over the years. These companies are in no position to throw out all their capital equipment. Furthermore, each of these services such as voice mail, call center, and other offerings involve adjunct servers, attached to the PBX fabric through proprietary line side ports or data interfaces. These applications do interoperate through standards, but at great cost.

The vast majority of PBXs are network islands connected via traffic-bearing circuits.

The SIP-PBX can work with legacy PBX implementations to bring these islands together, participate fully in forklift upgrades of already depreciated telephony infrastructure, and act as an overlay application to unify control of the VoIP network backbone. Furthermore, the SIP-PBX enables powerful services such as centralized voice mail for inexpensive storage, backup and regulatory compliance, corporate-wide directory for stronger customer service, global follow-me services for more productive employees, and many other applications that will drive successful penetration of this new technology.

The 3Com® VCX™ solution is the first product in the new category of SIP-PBX.
