New communication solution for TU Darmstadt
In January 2025, the campus-wide HRZ project UC changeover (unified communication changeover) was started.
The aim is to replace the existing heterogeneous telecommunications system at TU Darmstadt with a modern, IP-based unified communications solution. As part of the project, Webex is therefore being introduced as a new softphone solution.
Current status
The project is currently in the final stages of the pilot phase. In order to collect experience for the upcoming campus-wide conversion, suitable facilities were selected, contacted and converted during this phase.
Further information on the project plan, as well as instructions and help, can be found on our regularly updated website.
From now on: Softphones instead of hardware telephones when moving into new buildings
Prior to the planned introduction of Unified Communications (UC) at TU Darmstadt, only software telephones (softphones) will be used from now on when moving into new or complete refurbished builings. These will replace the desk telephones that have been used until now.
The Jabber client is currently used as the softphone solution. This will be replaced by the Webex client as part of the UC rollout. Hardware telephones (traditional desk phones) are no longer intended for use at employee workstations.
Necessary “function telephones” – where they are required by law (e.g. in first-aid rooms) – will continue to be provided.
Mobile communication
Jabber
The Jabber client offers video calls, chat functions, screen sharing and data exchange, among other features. TU Darmstadt employees with a personal phone number can also use the Jabber client for telephony services.
Office communication
The TU Darmstadt campus is equipped with two telephone systems. Find out which one is at your disposal.
