ISDN is retiring – How cloud telephony is making companies fit for the future

Urgent need for action in the transition

The ISDN shutdown is no longer a distant plan for the future, but has long been decided - and the clock is ticking. In Austria, for example, A1, the largest provider, has already taken concrete steps to phase out ISDN. All ISDN multiple connections will be deactivated by the end of 2025, followed by the last basic connections by May 2026. For companies, this means that existing ISDN connections will no longer be available in the immediate future. The costs for maintenance and support are already rising continuously, and spare parts are also becoming scarce. Those who act in good time not only ensure a stress-free, smooth transition, but also take advantage of the opportunity to benefit from the many advantages of modern cloud telephony earlier.

What is cloud telephony?

Imagine your own telephone system is no longer in the office, but in the cloud - that is, on a secure server that is accessible at any time and from anywhere. Instead of expensive hardware, a software solution is used that works over the Internet. This means no maintenance costs for the hardware and maximum flexibility and scalability.

For companies, it is not just this cost efficiency and flexibility that is beneficial, but also the extended functions that cloud telephony brings with it: from video telephony to seamless integration into CRM systems – modern communication à la carte, so to speak.

Mobile telephony and cloud telephone systems: an unbeatable duo

Mobile phones can also be integrated directly into a company's communications system using a cloud telephone system. Employees can be reached at any time, whether at their desk, from the beach office or on the move. And the best thing is: internal calls are free, regardless of where the teams are located.

Cloud telephone systems – the future of business communication

“A modern cloud telephone system like callit based on NFON/Cloudya combines all these advantages in one solution: easy operation, high security and absolute reliability," says Marco Gschaider, CEO of Iphos IT Service. "Our tailor-made advice makes callit the ideal choice for companies that want to face the new challenges of digital communication and at the same time optimize their communication costs."

The right time for the change

"The ISDN shutdown is unavoidable. Those who act early will not only save time and stress, but also money," concludes Gschaider. "And until the end of June, companies with the Business Premium tariff including flat rate for Austria for €9,90 per month can get a special treat for a flexible, future-proof and cost-effective switchover."
