PBX (Private Branch Exchange), Phoenix, AZ

A PBX is a phone system, which acts as a switchboard, allowing a business to reduce the total number of telephone lines they need to lease from the telephone company. In a traditional phone system a business leases a separate telephone line for every extension, including phones, faxes and peripherals like credit card processors. This is extremely expensive. With a PBX phone system the business can reduce the number of leased phone lines to about 10% of the total number of extensions they require.

Although the traditional PBX is a vast improvement over previous technologies, many businesses have searched for a way to integrate their PBX with VoIP (Voice over Internet Protocol) telephony. Using a virtual PBX (also called an IP PBX) phone system and VoIP phone service, a business can integrate voice and data networks into a single system, reducing costs, and improving functionality.

An IP(Virtual) PBX phone system is software based and often loaded onto a dedicated server which also acts as the VoIP system's connection to the internet. A virtual PBX replaces the PBX you use for your company’s landline calls. It is an electronic switchboard that receives, routes, holds, forwards to voice mail, or otherwise transfers calls over the internet.
