What is a IP phone?

On an IP phone, voice is carried via the Internet by establishing the connection from the phone to the traditional telephone network.

When will Swisscom switch from analogue telephony to IP telephony?

The switch has already begun and will be implemented until the end of 2018.

Who is affected by the switch?

All Swisscom customers who use the analogue fixed telephone network.

How do I switch?

With UPC, IP phones are already included in the cable connection. This means that you can simply activate your phone with us and continue making calls. For more flexibility and free calls to all Swiss fixed and mobile networks, we recommend Phone CH. With Phone International, you can also make free phone calls to fixed networks across 33 countries.

One call to 0800 66 0800 is all it takes and we will help you switch

Do those affected need to buy a new phone?

Almost all fixed network devices, such as IP telephones or analogue DECT (cordless) telephones, can continue to be used, though a RJ11 plug is a prerequisite.

Exceptions include rotary dial telephones, pulse-dialling telephones and ISDN devices, which cannot be used with VoIP. In these cases, UPC recommends buying a new fixed network device.
