On 17 June 2025, the Rectorate decided to introduce softphones as the standard telephone at TU Dresden from September 1, 2025. All personalizable telephones are to be replaced by softphones, starting with the existing ISDN connections. New personalizable phones will generally only be provided as softphones. Exceptions include non-personalizable telephones (laboratories, technical rooms, teaching rooms, consultation rooms, etc.), accessibility, and desk phones, which will be financed by the institutions themselves.
The softphone is an application (program) to be installed on a PC or smartphone and enables calls to be made with the business telephone number from the devices mentioned (e.g. also in mobile work). The entire range of desk phone functions (call forwarding, voicemail, call transfer, three-party conference, team calls, etc.) can be mapped on the softphone. The softphone is therefore a fully-fledged replacement for the desk phone. A softphone and the corresponding TU telephone number is always linked to a ZIH login, which is also used to log in to the application. A headset is required for the softphone on the workstation PC, just like for video conferences with BigBlueButton or Zoom. The softphone is available for all common operating systems in a supported variant: Cisco Webex.
