Do people still use PABX?
Absolutely — but they’ve evolved.
Traditional PBX (Private Branch Exchange) systems were built for analog phone lines, designed to share connections and route internal calls within an office. While those older analog systems are now considered legacy technology, the concept has evolved into IP PBX and cloud-hosted phone systems that use VoIP (Voice over Internet Protocol) instead of copper lines.
At Callryt, we’ve taken this evolution a step further. Our platform is built on the latest VoIP technology and enhanced with AI-powered features that make communication smarter, faster, and more efficient. From intelligent call routing to real-time insights, we’re constantly adapting as technology advances — so your business always stays connected and ahead of the curve.
PBX vs PABX — What’s the Difference?
Originally, PBX systems needed an operator to connect calls. When automation arrived, the term PABX (Private Automatic Branch Exchange) was born.
Today, all systems are automatic — and much smarter.
Callryt builds on this evolution with AI-enabled, cloud-hosted PBX that keeps your business connected, modern, and ready for what’s next.

Cloud Hosted PBX solution means that you do not need to invest money into sophisticated hardware because your entire phone system is hosted and managed in the cloud. You only pay for the services you need which release you from massive investment in capital expenditure and technical know-how required to set up your system.
​​
From the Service Providers perspective, the cost is generally shared between thousands of users which significantly lowers the per-unit usage/subscription cost for the customer when compared to the cost of fixed lines.
​
​Cloud Hosted PBX is not limited to any geographical location, which could lead to massive call savings for businesses that handle a large volume of long-distance calls. This means that your entire organisation regardless of where they are in the country can consolidate their communication infrastructure into a single system, making calls from one branch to another, seem like internal calls. The call plans which include unlimited calls to mobile numbers will lead to a significant reduction in average cost per call.
Cloud Hosted PBX empowers you to connect from anywhere in the country using your VoIP phone, a smartphone with software for VoIP, or desktop PC from any manufacturer. Now your employees can choose to work from home at any time with the same office number using their preferred device.
​
​With improved Quality of Service (QoS) schemes, better compression rates and high internet speeds, voice communication via the internet has improved tremendously. Before the commencement of your VoIP service, various tests can be carried out by your service provider to measure the quality of your internet connection to recommend the best VoIP solution for your location. Cloud Hosted PBX can now give you high quality calls over the internet with voice prioritisation and other packet loss resilience schemes. Many service providers now have their dedicated Fibre Broadband, 4G or ADSL networks which means that QoS schemes can be applied holistically from the central office to the subscriber guaranteeing excellent quality voice calls.
