Traditional, on-premise PBX systems require hardware, license fees, and specialized technicians to maintain. A cloud PBX on the other hand, provides all of the phone features that a modern business needs to communicate, at a much lower cost and with more accessible functionality.

Cloud phone systems use Voice over Internet Protocol (VoIP) technology to make and receive phone calls. VoIP technology uses the internet to route telephone calls between end points using the industry standard of Session Initiation Protocol (SIP) to set up calls between phones.

With a cloud-hosted PBX, all of the services, features and functionality of the phone system are accessed via the internet rather than from a complicated box of technology, cables, and switches on site. This also means that any new upgrades and features that the service provider releases are added to your phone system immediately.

Since phone system services and actual call flow routing commands are running in off-site data centers, there is no hardware needed to run a cloud PBX. The hosted PBX works with your existing internet connection, and even desk phones are optional.
