UOL's telephone system is outdated and there are no longer any spare parts for it. Despite the outdated technology, new connections are constantly being added. The current telephone system (originally installed around 1997) can no longer cope with this reliably. UOL's telephone system needs to be replaced to ensure that employees can be reached without disruption.

The major project "Conversion to VoIP telephony" pursues the following objectives:

• The currently available functionalities will be covered with more modern, user-friendly services.
• The telephony solution is flexible in terms of location and thus supports hybrid working models.
• The stability and availability of central service numbers is guaranteed (InfoLine Studies, Service Desk, Administration).
• The processing of communication data is GDPR-compliant.
• The new processes to be set up are integrated into or linked to existing databases (SAP, identity management).

• The everyday working life of employees is made easier; accessibility is also simplified in mobile work / teleworking.
• The existing workplace equipment (PC, headset) is utilised and resources are conserved as a result.
• Voice quality is improved; reliability is high.
• The infrastructure is future-proof.
• The IT security architecture is strengthened.
• Service numbers are reliably accessible for enquirers.
