What is a Cloud PBX?

What is a Cloud PBX?
Published on:

A cloud PBX is a business phone system that is hosted entirely on servers in off-site data centers and powered over the internet. A cloud PBX can provide even more features than a traditional PBX phone system, while enabling a non-technical administrator to easily set everything up.
Letís start by breaking down cloud and pbx.
Cloud is a broad term for software and services that run on the internet. Pretty much everything these days runs ìin the cloudî.
PBX stands for Private Branch Exchange, which is a private telephone system that enables an organization to communicate internally as well as externally. The PBX is the ìmachineî that routes incoming calls, enables you to transfer calls to other extensions, and houses all the specifications of how your phone system should work.
Traditional PBX versus cloud PBX
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.
A better design for your phone system
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. A business can choose from IP phones, softphones, and mobile devices. A mobile app installed on a userís mobile phone enables them to connect to the cloud phone system. Since thereís no physical PBX to configure, the routing of calls to IP phones is done using a simple drag-and-drop editor for managing services called a Call Flow.
Geographical redundancy gives you more reliable phone service
Telzio uses multiple data centers in dispersed geographic locations to house servers for failover redundancy. Redundancy means that Telzio data center servers have exact replicas so that if one fails it can be automatically replaced (failover) by another to avoid downtime. This setup also enables call routing efficiency so that multiple offices and mobile users have high quality calls wherever they are located.
Security in the digital age is always a growing concern and ensuring it through a cloud PBX system is paramount. Telzio utilizes highly secure data centers with extremely robust security measures for the data center and its servers. We also provide VoIP security tips and services like two-factor authentication to ensure that you can secure your phone system on your end.
