What is CERNphone?¶
CERNphone is the softphone solution provided by IT department. It replaces CERN's legacy Skype for Business and Alcatel telephony services. CERNphone consists of a dedicated SIP backend, configuration and provisioning web interfaces as well as two phone applications:
- CERNphone mobile: A mobile softphone app for iOS and Android customised to CERN needs (based on the popular Linphone open source VoIP client).
- CERNphone desktop: A softphone app for Windows, macOS and Linux developed at CERN.
Recent presentations on CERNphone can be found here:
A CERN Bulletin article on the Skype for Business phaseout (end of June 2022) can be found here.
There are several drivers behind CERNphone:
- Focus on software based solutions replacing physical phones and avoiding associated costs (such as purchasing, installation and renewal of IP phones, networking switches and outlets, cabling)
- Reduce costs originated by mobile calls - CERNphone calls are cheaper as handled by our fixed telephony operators, even when on data roaming
- Use fixed telephony phone numbers owned by and reserved for CERN, rather than mobile numbers that may change again on future tenders.
- Features of the service, as well as a comparison with Skype for Business, are found here.

- All CERN classes of personnel and users that are authorised to obtain and use a CERN fixed telephony number can install and use CERNphone.
