All-IP: What does the switch from ISDN to IP mean for companies?

What is All-IP?

All-IP stands for "All Internet Protocol" - the standardization of all communication services via a single, digital network.

This means that
telephony, Internet, fax and other communication services no longer run over separate lines, but over a shared IP-based network.

In plain language:
In the past, telephone calls were made via the classic ISDN or analog network. Today, voice is transmitted via the internet protocol - similar to surfing the internet or streaming videos.

You can find out why the switchover is now unavoidable for companies in the article "ISDN switch-off Austria - What companies need to know now!".

The great advantage of All-IP lies in its efficiency and flexibility: companies can bundle voice and data services, manage their communication systems centrally and thus reduce costs.

What is the switch from ISDN to IP?

The changeover from ISDN to IP - also known as an all-IP changeover - means that existing ISDN or analog connections are migrated to a pure IP-based infrastructure. This affects all companies that previously relied on ISDN telephone systems.

During this changeover, ISDN lines are deactivated and telephones, routers and PBXs are upgraded to VoIP technology (Voice over IP) or replaced. Communication systems are connected to the modern IP network.

If required, cloud Cloud telephone systems can also be integrated - for more flexibility and location-independent collaboration. Avoidable mistakes are often made when switching from ISDN to cloud telephony. We show you the "5 most common mistakes when switching - and how to avoid them!"

It is therefore necessary for companies to check their existing hardware and switch to all-IP-capable devices if necessary. If you want to switch your analog telephone to IP, you should also keep an eye on the network infrastructure - because IP telephony can only make the most of its advantages with a stable Internet connection.

Anyone who wants to switch their analog telephony to IP telephony today will benefit in the long term from

• Lower operating costs
• Better voice quality (HD Voice)
• Future-proof solutions for hybrid and mobile working models

Conclusion: Switch from ISDN to All-IP now

Switching from ISDN to IP is more than just a technical update - it is a step into the digital future of communication. Companies that switch their analog telephony to IP today will benefit from more flexibility, better voice quality and lower costs.
