Key Systems Superseded by the IP-PBX

Key systems were designed to serve the communications needs of small business. Using low circuit-to-user ratios, the typical key system can support calling patterns of approximately a dozen users. The key system classically rings all phones, makes every line appear on every phone, and forces the user to select an available outbound circuit before dialing.

PBXs can concentrate all calls to a switchboard or support unique telephone numbers for each extension if desired. Unlike with key systems, outbound calls are handled on a shared basis, not requiring any user activation other than through the number dialed.

Because PBX services in the past have been more expensive than key systems where low-user numbers exist, many organizations have had to choose the lower cost and less sophisticated features of the key system. Now these users can gain enterprise-level services via IP PBX solutions. The IP PBX offers to enterprises of all sizes the professional call handling capabilities of the PBX. For example, the 3Com V3000 IP Telephony Solution delivers large enterprise features such as ACD, hunt group, auto attendant, and voice mail to small businesses and to the small sites of large enterprises.
