Traditional landlines

Background

Over time, several fixed telephony technologies have been implemented at CERN and coexist until now:

 CERNphone consists of a dedicated SIP backend, configuration and provisioning web interfaces as well as two phone applications:

  1.   CERNphone mobile: A mobile softphone app for iOS and Android, based on the popular Linphone open source client and customised to CERN needs.
  2.   CERNphone desktop (pilot phase): A desktop softphone for Windows, macOS and Linux developed at CERN. 
  • Skype for Business (SfB): deployed at CERN since 2013. This telephony solution is replaced by CERNphone. If you are about to create a new phone number, unless you have a justified need for using Skype for Business telephony, you should create it directly on CERNphone (see CERNphone: migration and installation guide). 

  • IP Alcatel phones: deployed between 2006 and 2014. Currently, only people having already an IP Alcatel device can still request for a new phone number. Purchasing new IP Alcatel devices is no longer possible.

  • Analogue phones: obsolete fixed phone technology, deployed until 2009. The replacement of the analogue phones is ongoing, they are not installed or maintained anymore.


Moving of traditional phone lines

Instead of moving your traditional phone line, you need to migrate to CERNphone following : Migrate to & install CERNphone.
