ISDN successors and alternatives - Why companies should rely on cloud telephony and VoIP now.
The switch-off of ISDN is forcing many companies in Austria to rethink their communications infrastructure. But what successors are there to ISDN, what alternatives make sense and why is it worth switching now?
What successors are there to ISDN?
The direct successor to ISDN is Voice over IP telephony (VoIP). Voice data is no longer transmitted via separate lines, but as data packets via the Internet or a private IP network. This makes conventional ISDN connections superfluous. In addition to traditional voice transmission, video conferencing, chat and collaboration tools can also be integrated.
Cloud telephone systems, which offer all the functions of a conventional ISDN system but do not require their own hardware on site, are particularly popular today. Updates, maintenance and scaling are carried out centrally from the cloud. However, if you want to continue working with a classic desk phone, the Cloud telephone system from CANCOM Austria is ideal. It combines modern soft clients for smartphones and PCs with a large selection of compatible end devices.
Switching from ISDN to a cloud telephone system offers companies great opportunities to sustainably improve communication and efficiency. At the same time, errors often occur when switching from ISDN to a cloud telephone system, but these can be easily avoided. To ensure that your company doesn't fall into typical traps, we have summarized the 5 most common mistakes when switching and show you how you can easily avoid them.
What are the alternatives to ISDN?
The most important alternatives to ISDN are
VoIP connections with the provider: SIP trunks replace the ISDN system connection and connect existing PBXs to the IP network.
Cloud telephone systems: Complete solution without your own hardware on site. Perfect for companies with multiple locations or home office employees.
Hybrid solutions: Combination of classic telephone system and IP connection - useful as a transition scenario.
What does the switch from ISDN to IP mean?
The switch from ISDN to IP means that telephone connections are no longer operated via the classic, circuit-switched ISDN network, but via the Internet Protocol (IP). Instead of separate voice channels, telephone calls are transmitted as data packets via the same network that is used for the Internet and e-mail.

The ISDN switchover to IP is the step from an old, line-based technology to a modern, standardized and digital communication platform.
Conclusion: Companies that are still using ISDN should switch to cloud telephone systems and Voice over IP telephony now. The advantages are obvious: lower costs, better scalability, integration into modern collaboration tools and maximum flexibility - whether in the office, home office or on the move.
