WHAT’S OCCURRING?Openreach has announced it will be switching off its PSTN and ISDN networks in 2025 in favour of IP voice services, with a gradual phase-out of the older systems. At this point, Openreach will cease taking ISDN orders, and all businesses will be forced to find other IP-based options for their business telephony systems
WHAT IS ISDN AND PSTN?The Public Switched Telephone Network (PSTN) is the familiar landline telephone system originally set up for analogue voice communication, and became the most reliable method of making voice calls and the main carrier for internet activity across the world. Then came along the Integrated Services Digital Network (ISDN), allowing the digital transmission of voice, video and other services simultaneously, using the traditional PSTN network.
WHY ARE THEY BEING PHASED OUT?
These businesses need to be made aware of the upcoming changes so they can begin the necessary switch to IP-based services such as SIP and VoIP to avoid finding themselves without a phone system.
WHAT IS SIP AND VOIP?Session Initiation Protocol (SIP) is a protocol used in Voice over Internet Protocol (VoIP), and allows users to make voice and video calls on a global scale using computer and mobile devices with an internet connection.
The biggest and most noticeable difference between traditional ISDN and SIP networks for businesses is the flexibility of not being tied down to a fixed line at a fixed location, allowing you to have the ability to mobilise your business communications. These VoIP communication systems are also often referred to as cloud-based telephony systems.
Organisations switching to a cloud-based system can save
on costs as well as providing a range of extra features.
However, you will need to look at whether your existing internet
connection is up to the job.
AFTER THE SWITCH OFF
The benefits to your business of implementing the right data connection go beyond cost efficiencies and speedy web browsing. This increased speed, reliability and reduced latency enables you to take full advantage of bandwidth-intensive and real time applications in the cloud. You need Ethernet solutions that provides dedicated internet access with guaranteed speeds and service level agreements that offer rapid response times.
