PBX hardware (PBX phones) is a mature technology that offers many benefits for the right type of application. As a minimum, multiple extensions in a single office can share the cost of incoming phone lines. It is not necessary to pay for a separate phone line for each extension. Capital costs for the equipment can be amortized and depreciated over time. Even though system management and maintenance continues to add cost after installation, today's systems are more robust and easier to manage than they have been in the past. Incoming calls are typically free or very low cost. In more expensive systems, some level of system expansion is allowed for scalability. Businesses that can reliably predict their needs can usually find a cost-effective system. As features and functionality continue to be added, a PBX device can add productivity to an office environment. Almost any feature that can be imagined for telecommunications can usually be found somewhere among the many vendors and offerings in th is space - as long as customers are willing to pay the associated price.
