ISDN & PSTN Switch Off 2025
ISDN (Integrated Services Digital Network) and PSTN (Public Switched Telephone Network) are telecoms systems that have entered a phase out stage, with the switch off of these legacy platforms Scheduled by the end of 2025.
At One2Call we are helping businesses to transfer away from these legacy telecommunications systems to a modern, future-proofed form of business telecoms. We are working along side businesses to understand what they need out of a phone system and build a modern, easy to use solution that will last them for years to come.
Why is ISDN & PSTN being switched off?
Neither of these older platforms are able to keep up with the large quantity, or quality, of telecoms solutions that we have seen adopted in the evolving digital landscape. These traditional lines also offer very little flexibility and are costly to upgrade and maintain. As such, both ISDN and PSTN have entered a phase out stage with the switch off scheduled by the end of 2025, with many businesses transitioning to newer SIP and VOIP based services, which offer a more modern, easy to use and maintain platform that can deliver higher volumes of calls in higher quality.
To maintain a business phone system, businesses must upgrade from these legacy solutions before the 2025 switch off date, or they will risk losing service entirely.
One2Call have already helped 1000’s of businesses switch to a new and future-proofed platform that provides the same features as traditional systems and much more besides. newer systems such as 3CX can offer Easier Management, Inteligent Call Routing, Web Chat, Conferencing Solutions and even Video Calling. These modern systems can also ‘free’ your phone from your desk and even from your physical location. Providing solutions that allow you to make and receive calls from Desktop, Mobile and even from a web browser. They can also be easily scaled from a single user with a smartphone app, to 1000’s of users in a call center.
