SIP credentials allow to use the Swisscom landline number on third party devices and VoIP clients. Customers can activate and manage the service from now on in their customer center (www.swisscom.ch/login) under "Fixed network" – "HD-Phones". You'll find more information on SIP credentials and a configuration manual here.
Please note that Swisscom will not provide any support for the SIP credentials.
