Jabber client: How to install and use

Use of the Jabber client

Step 1: download the client

Please install the client.

Step 2: Link between login and phone number

The central login must be linked to the phone number. The Jabber client with the business phone number can then be used for incoming and outgoing phone connections.

Please contact servicedeskattu-freiberg [dot] de. In order to minimize the effort, we do not recommend individual requests. Ideally, the decentralized administrators provide us with the most complete possible list of login phone number assignments.

Step 3: client setup (Windows 10)

Note: In order to be able to use the Jabber client from outside the university (campus data network), an active VPN connection must exist (as described here: https://tu-freiberg.de/en/urz/anleitungen/vpn).
