Video Conferences at HZDR

Professional video conferences can be done in several video conference rooms at the HZDR sites in Dresden and Leipzig. The connection is possible via internet (h.323 over IP) or telephone connection (ISDN up to 512k). For multipoint conferences the DFN gatekeeper can be used (see below).


  • Using the calendar functionality of the intranet-portal (select building and room, please give the VC-target in the comment) all VC-rooms can be booked.
  • contact: department Information Technology, office (telephone number: 2190)
  • Apply for a multipoint-videoconference at the Gatekeeper DFN → Conferences
    Procedure: Start, reserve ID, define password, take control, works ad-hoc, without extensive reservation!
    DFNConf based conferences can be joined via VC-System, any H.323/SIP compatible client, a webbrowser (no installation necessary), via phone.
    Strong recommendation: there are about 30 different VC systems/providers which do not correspond (e.g. Zoom can not talk to WebEx). Most of these require the installation of a propieritary client.
    Please keep in mind, GoToMeeting and BlueJeans can not be used with our VC hardware, WebEx only with external invitation, you have to use your own PC and your own hardware (camera, microphone/speaker with echo cancelation).
  • For lectures or seminars with a large number of participants, you might want to use our own Big Blue Button server A webbrowser and your own hardware is required only. We strongly recommend using a headset.
