Configuring local IP phone credentials on your Internet-Box and SIP phone.

What are local IP phone credentials?

You can use your Swisscom fixed network number on SIP-enabled external devices or appropriate software using the “Local IP phone credentials” function (max. 10 connections). The SIP standard (Session Initiation Protocol) is a communications protocol used predominantly in Internet telephony (VoIP).

The SIP phone must be connected to the Internet-Box in your home. The devices in question need to be configured correctly to use this function. Contact our chargeable support service for personal advice and assistance.


Making calls using the Home app

The Home app telephony function offers you the convenience of making and receiving fixed network calls at home through the app using your home network. The app works like an extra IP fixed-line telephone (handset).







Configuring the Internet-Box

In the Internet-Box web portal, you need to set up a connection, with an individual user name and password, for each SIP device. All additional parameters will be generated automatically by Swisscom and listed in the web portal.

To configure local IP phone credentials, enter the following address in your browser http://internetbox or 192.168.1.1. This will take you to the Internet-Box web portal. Please note that you will need to be connected to your WLAN at home.






Configuring the SIP telephone

After setting up your SIP telephony credentials in the Internet-Box web portal, you need to enter the credentials on your SIP device. Installation examples follow. Please note that exact parameter names may vary depending on the provider. In the pictorial instructions that follow, the same sample values are used throughout.






The Snom D715 corded telephone supports the “Power over Ethernet” function. It is therefore sold without its own power supply. You will need a 5 V/2.1 A power supply to use the Snom D715 with the Internet-Box.


Information on SIP credentials

SIP credentials are confidential login details for using the fixed network number on devices and third-party VoIP clients not supported by Swisscom. Once configured, you can make calls anywhere in the world subject to your subscription. These calls are charged in accordance with your fixed network subscription and appear on your invoice.
