What is CERNphone?¶

CERNphone is a softphone solution provided by the 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.

Why CERNphone?¶

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 - calls placed via CERNphone to non-CERN numbers are much cheaper than those placed via CERN's mobile subscriptions, 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.
