Visit the Customer Center to order additional phone numbers (not possible for SwisscomLine plus): Got to "My products & services" > "Telephony" > "Adjust telephony options"
If you use an Internet-Box, you can assign phone numbers to devices as follows:
If you have a Centro Business, you can assign phone numbers to devices in the Customer Center:
Would you like people to be able to look you up in the public phone book? An entry in the official local.ch directory ensures your phone number and address are listed in both the printed and electronic phone book. You can register your number and address online and edit or add to the entry at any time (e.g. when you change address, get married, have children etc.).
Deactivate address updating in the Customer Center to prevent your address being passed on to third parties.
If you want to prevent your fixed network number or name being displayed to the call recipient, you can suppress your phone number. You will then appear to the call recipient as an anonymous caller.
If you wish to set this permanently for your fixed network phone, please go to the Customer Center. To suppress your number for one call, enter *31, then the call recipient’s phone number, followed by # (e.g. *310449999999#). This additional service is free.
If you wish to suppress your mobile phone number, enter *31#. You can deactivate the service again by entering the code #31#.
If several telephones are registered on your Internet-Box, you can use them to make free internal calls. You don’t need more than one phone number for this. Simply assign individual internal numbers to the phones in the web portal (http://internetbox.home or 192.168.1.1) .
You can also make internal calls and forward them for free with a Centro Business 2.0. Call forwarding on a Nyon HD-Phone, Gigaset SL360HS and Gigaset CL660HX is easy, and you don’t need an additional phone number. However, you do need an additional phone number/line to forward calls on an IP-Phone (e.g. Yealink T46G, Sarnen HD-Phone) with inOne SME Office.
Example with an Internet-Box: Assign the number 201 to your handset in the living room. You can then dial the internal number 201 on the handset in the bedroom to ring your phone in the living room.
You can also forward an external call to another internal handset. Proceed as follows:
With an Internet-Box, calls can be forwarded from HD-Phone to HD-Phone and from HD-Phones to a phone connected to the Internet-Box telephone line 1 or 2. No other internal forwarding, for instance to a Yealink T46G IP-Phone, is possible.
If you have a cordless HD-Phone you can access your contacts in the main phone book from various handsets.
With an Internet-Box:
Manage your contacts in the web portal (http://internetbox.home or 192.168.1.1). You can, change and delete contacts in the “Telephony” > “Phone Book” menu. Please note that you only have access when your home network is connected to your Internet-Box.
The Home app also lets you transfer your contacts from your smartphone to the Internet-Box phone book. The phone book is automatically saved in the Swisscom network and is restored to the default setting following a router change or reset.
With a Centro Business 2.0:
Manage your company telephone directory in the Customer Center. You can manage internal and external phone books with up to 500 contacts with “Business Telephony” > “My Phone Numbers”. Please note that contacts created in the Customer Center cannot be edited or deleted on the handset.
