Videoconferencing

Videoconferencing will be available, hosted on the CERN Vidyo system, including a H323 capability, SIP dial-in, and PSTN. To connect:
  • Connect using WebRTC to https://vidyowebrtc.web.cern.ch/?key=2KK49yAwGGzJ (experimental)
  • Connect with H323 or SIP to vidyogw.cern.ch (188.184.66.56) and enter conference ID: 109338677#
    Alternative endpoints are at vidyogw04: 188.184.67.151, or try one of the old vidyo servers at e.g.: 137.138.248.204
  • Connect with H323 to cern-vidyo-gateway0.internet2.edu (207.75.165.80 and [2001:48a8:68fe:5::80]) and enter conference ID: 109338677#
  • The vidyo client is also available for mobile platforms like Android and iOS. It is also available for various Linux flavours.
  • Direct SIP connections to sip:109338677@vidyogw.cern.ch ... or enter code 109338677#
  • Call one of the following dial-in numbers and enter conference ID "109338677#":
    • +31 20 7165248 (Amsterdam, NL)

    • with a Nikhef lab phone, dial +31 20 592 2263 and enter code "109338677#" after the prompt for a free call from your mobile (lab phone users only, otherwise regular charges apply!).
  • See CERN Vidyo documentation for more solutions
    Download the full desktop client for chat support and participant listing from the CERN website or here for windows, linux, debian, RPM/RedHat, and Mac.

End-point device hints

  • On Polycom (HDX) devices, use the pound sign to bring up the dialpad, so you can then enter the conference number
  • If your H.323 endpoint is unwilling to connect to the IP address (or to vidyogw.cern.ch) and returns "unknown number" or a similar message, try to remove any "gatekeeper" configuration from the system settings menu (look for "gatekeeper", or E.164 settings)
  • There are many H.323 clients that use your own laptop as an end-point: cross-platform open source clients like Ekiga, and Windows clients like Polycom RealPresence Desktop, or Polycom PVX.
  • Quality really depends on your connected audio and video equipment. Use hardware echo cancellation: e.g. a Duet USB speakerphone, or a Logitech BCC950. Small investment, big improvement!
