Adam Simpson, chief technology officer at Easy Office Phone (, says:

Why is hosted telephony gathering so much attention?

In short, the Hosted PBX concept offers a great deal of power, flexibility, and scalability to end users at a very cost-effective price point. Compared to traditional phone service options, the Hosted PBX is revolutionary. The end user requires comparably little new on-site equipment (none at all, in some implementations), reducing capital expenditure, ongoing maintenance/upgrade costs, and staff time commitments. Equally important is the powerful feature set available to customers – our hosted PBX system delivers an advanced set of features such as free North American long distance calling, main menus (autoattendants), ring groups, after-hours call routing, and much more. Employees can work from any physical location, allowing for decentralized offices which can produce a variety of cost savings and related benefits.

A Hosted PBX implementation generally assumes Ethernet connections at each seat. If these are already in place, rewiring is typically not needed – many VoIP phones offer dual Ethernet ports, allowing the phone to act as a gateway for the computer. Implementation of a VoIP Hosted PBX service over a wireless local network is not typically recommended, however.
