ISDN switch-off Austria - Everything you need to know!

The ISDN switch-off in Austria is progressing, as ISDN connections are now obsolete. For many years, ISDN (Integrated Services Digital Network) was a proven technology for telephony and data transmission. However, the digital world is evolving and ISDN is now considered obsolete. New ISDN lines are no longer available and existing ISDN lines are being deactivated by providers.

Why switch from ISDN to Voice-over-IP?

As a result of the ISDN shutdown in Austria, many providers are terminating their old ISDN lines. Anyone who still has such a connection should switch to a modern alternative soon, as no new ISDN connections will be issued. Compared to ISDN, Voice-over-IP (VoIP) telephony offers considerable advantages in terms of costs, flexibility and future-proofing. Voice-over-IP telephony is the future of communication and the standard in modern corporate communication. It makes it possible to transmit voice services via the Internet instead of conventional telephone lines.

Advantages of Voice-over-IP telephony for companies:

Cost savings: voice-over-IP reduces the cost of telephone lines and long-distance calls as communication takes place over the Internet. This offers enormous savings, especially for international calls.
Flexibility: With Voice-over-IP, you can make calls from anywhere as long as you have an Internet connection. This enables home office and mobile communication without restrictions.
Scalability: VoIP systems are easily scalable and can be easily adapted to the growth of your company.
Additional functions: Voice over IP telephony offers many useful features such as voicemail, call forwarding, conferencing, call recording and much more - all integrated into one system.

From the ISDN switch-off in Austria to VoIP

Frequently asked questions about ISDN switch-off and Voice-over-IP

Why is the ISDN switch-off taking place?
ISDN is being switched off because the telecommunications networks are being converted to modern IP technology. Voice-over-IP (VoIP) offers more flexibility, better voice quality and is future-proof.
When will the ISDN switch-off take place?
The ISDN switch-off will be carried out in stages. Many providers have already announced fixed dates from which only voice-over-IP connections will be available.
What does the ISDN switch-off mean for my company?
After the ISDN switch-off, existing ISDN telephone systems can no longer be used directly. You will have to switch to Voice over IP technology in order to continue making calls.
What does Voice-over-IP (VoIP) mean?
With Voice-over-IP, the voice information is not transmitted via separate connections/lines (ISDN/analog), but the voice is transported via the Internet in the form of IP data packets. This eliminates the costs for separate cabling and components, as is the case with conventional telephony.
How do I know if I am still using ISDN?
You will recognize it immediately from your last provider telephone bill. The costs for the ISDN connection are listed at the top of the bill. In order to optimally develop a complete concept for a CANCOM VoIP telephony solution, please upload a photo of your provider bill in the contact form in addition to your contact details and requirements. This will enable us to provide you with a customized offer for a "state of the art & fit for the future" communication solution.
When will the analog telephone lines be switched off?
Traditional analog home telephone connections are being switched off by providers at the same time as ISDN. For private home users, the providers usually provide DSL Internet modems to connect the existing analog home telephone. ATTENTION: this usually involves considerably higher costs. If you are currently using analog telephone connections for your business, we will be happy to develop a modern VoIP-based solution for your future communication requirements.
I have received the information about the ISDN switch-off, do I have to do anything now?
Yes, we recommend contacting us to work out the optimum solution for you.
Will my costs or conditions change if I switch to VoIP?
Yes, the migration to SIP/VoIP and the SIP trunk services offered by CANCOM result in a considerable cost advantage.
What does Internet telephony cost?
The costs for Internet telephony consist on the one hand of the ongoing provider costs for the SIP numbers and the call minutes used, and on the other hand of the telephony solution used. With the CANCOM SIP trunk provider services in combination with our cloud or on-premise telephony solutions, we put together an attractive overall package for you with no hidden costs at a future-proof price.
What do I need to make calls over the Internet?
In order to be able to make calls via the Internet, your existing ISDN telephone number must be converted (ported) to SIP. We offer the complete package for SIP lines and Voice-over-IP.
Do I need a new telephone system?
By migrating to SIP, telephony can be made available directly from the cloud. If your existing telephone system is a newer model, we will be happy to advise you on the extent to which this system can be connected with SIP trunks.
Do I need a telephone for Internet telephony?
No, by using Internet telephony (VoIP) it is common to make calls directly via your PC workstation using a softphone and connected headset. This eliminates the need for telephones and cabling. Nevertheless, it is still possible to set up your own VoIP telephones so that you can make calls without a PC.
Which telephone can I use for Internet telephony?
Usually, either softphones (program on your PC workstation) or VoIP telephones are used for Internet telephony. However, it is also possible to connect classic analog telephones (e.g. for a hotel) to modern VoIP telephone systems via so-called VoIP/analog gateways. This means that every connection where a telephone is required does not necessarily have to be equipped with network cabling.
How do I connect a Voice-over-IP telephone?
A VoIP telephone set is usually connected via an RJ45 network connection. In addition, a VoIP telephone requires a power supply, either via POE (Power over Ethernet) or a local plug-in power supply unit. Our solution experts will be happy to work with you to plan the optimal use of your existing network infrastructure and advise you on any additional requirements.
