With fixed network telephony (IP), you connect your fixed-network telephone to the Internet-Box instead of a phone socket.
How it works:
If you hide your landline number, you can call anonymously. The person you call will not see your number.
How it works:
Enter the following key combination on your fixed-network phone: *31 followed by the telephone number.
Order an additional fixed network number in My Swisscom(opens in new tab). Go to Manage products and services Telephony Change options.
Private individuals can use two numbers, business customers up to five. Need more phone numbers? Contact us.
Then set up the phone number on the device:
If you have two or more fixed-network telephones (HD-Phones) connected to the Internet-Box, you can make calls from one to the other free of charge. Simply allocate short numbers to the devices in the web portal (http://internetbox.swisscom.ch or 192.168.1.1). You can then dial the short numbers to call another fixed network device internally.
Internal forwarding is possible only from one HD-Phone to another HD-Phone or to a telephone that is connected to phone port 1 or 2 on the Internet-Box.
The same also works with Centro Business. However, an additional phone number is needed in inOne SME for forwarding to an IP telephone (e.g. Yealink T46S).
