Since 2017, all Swisscom customers have been making calls via the Internet using fixed network telephony (IP)
With fixed network telephony (IP), fixed-line telephones are connected to the Internet-Box and not directly to the telephone socket as they were in the past. The Internet-Box must be activated to make calls.
If your fixed-line telephone is not IP-enabled, you can still use it (e.g. older analogue telephones). However the latest generation of IP-compatible telephones ensure that you can enjoy all the benefits of new fixed network telephony.
The Internet-Box has an integrated telephone base station. It can wirelessly connect all Swisscom HD-Phones to the Internet-Box at the touch of a button. You can then connect the telephone charger to any power socket you like. Another advantage is that from now on, you can make calls in HD quality. You can wirelessly connect up to four 5 HD-Phones to the Internet-Box.
When you use an HD-Phone for the first time, the handset display will automatically request you to press the + button (= pairing button) on the Internet-Box (base station). This sets up the phone in just a few seconds.
If your HD-Phone loses its connection to the Internet-Box, because you have changed router, for example, check the instructions to see how to reconnect using the menu on your telephone.
This video shows you how to connect your telephone with the Internet-Box.
Fixed-line and cordless telephones with their own DECT base station are now connected to the Internet-Box rather than directly to the telephone socket as they were in the past. Use a port labelled “phone” on your Internet-Box for this.

If you are unable to establish a connection with your fixed-line phone, please change to frequency dialling in the settings (if possible). Telephones with impulse dialling can no longer be used.
Check the following points:
To ensure that you can still receive calls if there is a power cut or a connection problem, activate the supplementary service “Forwarding in the event of faults” in the Swisscom Customer Center. You can set a number there to forward calls in the case of such a situation cropping up.
If the connection problem persists, please contact us.
The names of callers who have suppressed their own telephone number or name display do not appear on your telephone. The names of persons who are not registered in the publicly accessible local.ch telephone directory do not appear either.
Alongside your usual telephone, you can also make and receive fixed network calls using the Home app when you are connected with the WLAN at home. The app works like an extra IP fixed-line telephone (handset). The telephony function lets you view your fixed network call log, manage the main Internet-Box address book and suppress incoming calls. You can register up to10 apps with the same fixed network number. More information on the Home app.
