VC FAQ

The recommended software client is Lifesize Softphone (former Mirial Softphone). This sofware client runs on MAC and Windows computers and is capable of videoconferencing resolutions up to 1080p (depending on used hardware), it costs approx. 120 €.

We recommend the WebCam Logitech C920 (~ 80 €) and, to assure echo free audio without headset, the Phoenix Audio Duet PCS (USB microphone & speaker combination device, ~ 140 €).

An E.164 Number is a Number following the Global Dialing Scheme. The numbers resemble phone numbers and are hirarchically organized by world gatekeepers, country gatekeepers and local gatekeeper zones. Example the number 0049 893299 6005 routes the call via the German country gatekeeper 0049 to RZG's local zone 893299 and the extension (namely one of the vc groups hardware systems) 6005.

Please contact the videoconferencing group by e-mail and submit the following information:

• your institute's name
• your name, phone number and e-mail address
• the type of your VC-system and its IP address
  

You will be contacted and provided with your E.164 number, your H.323 Alias name, the IP address of RZG's gatekeeper and some hints for your firewall setup.

Alternatively, if from Germany, you could register with GWDG or the DFNVC.

If you are not working for a German institute please look up your national H.323 provider in the following link:
