This service is responsible for the installation, configuration, operation and maintenance of the fixed line telephone infrastructure and services including IP telephony, the call centers (Fire Brigade, Service Desk, IT Helpdesk) and telephone switchboard.
Over time, several fixed telephony technologies have been implemented at CERN and coexist until now:
CERNphone: CERN's new softphone solution developed by IT department. Users having already a personal number (analogue, IP Alcatel or SfB) can migrate their number to CERNphone. Newcomers are also welcome to create their personal CERNphone number (see KB0007095).
- Skype for Business (SfB): deployed at CERN since 2013 and 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 mobile: 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.
