2019 WW: Voice problems with Vivox on your grid? Suggestions for plan B

Voice problems with Vivox on your grid? 
Suggestions for plan B

Vivox has demonstrated that it can be out for two weeks or longer.  For educational or most business uses that is a single point of failure.  An alternative is needed.  Some grids may offer fallback options.  Web-worlds can provide a fast fallback with no advance preparation.

Possible voice emergency alternatives to Vivox

Web-worlds are alternatives

  • 3DWebWorldz
  • CybaLOUNGE
  • You can visit either of these as a guest, without registering.
  • No preparation needed.


Emergency voice alternatives


  • Discord runs in a browser or an installed ap.  
  • Discord (Wikipedia)
  • Someone sets up a server for a group and creates sections as needed.
  • Others in the group are invited to join.
  • Some sections are for text; others are for voice.
  • Community members can send messages to individuals or to the group.
  • Discord offers easy communication without logging into the grid.
  • Discord can run in a browser and support voice there.
  • Discord easily runs along with an OpenSim viewer.
  • So users can use Discord for voice while in OpenSim.
  • A group might want to maintain a server for regular use by its members.
  • The text chat feature would encourage more and faster communication.
  • Educators might not like its promotion as a connection for gamers.
  • Ask discord questions


  • Most web-savvy people have Skype and are familiar with it.
  • It is not designed for group meetings and is not easy to use for that purpose.
  • I work with one group that has a board meeting in Skype.
  • It works, but only because some participants keep track of Skype changes.
  • I would not recommend Skype for larger groups.

Quick trip to a web-world

  • You visit a web-world with a click on a web link.
  • No downloadNo install.  No registration.
  • You can enter as a guest by entering a name and choosing an avatar.
  • People who don't enter a destination will all go to the same place.
  • People can talk by clicking on a mic graphic near the bottom of the page. 
  • To move forward, you click on the screen and then use the up arrow key.
  • In 3DWebWorldz everyone will come to the orientation center.  
  • That center has displays to tell you how to go places and do things. 
  • But you can stay and hold your meeting if no one else is there.
  • In CybaLOUNGE people may want to get instructions from here:
  • What guests can do in Cybalounge and how. Tutorial
Cybalounge login panel

Plan B for grids

  • Commercial grids may want  to set up a plan for backup voice.
  • Voice alternatives may not offer lip movement and green waves.
  • But they could offer connection to people not inworld.  
  • Grid owner's viewpoint:  Marketing and product differentiation.

Discord in the viewer

  • Could be offered as an independent option in a customized viewer.


  • FreeSWITCH "...a scalable open source cross-platform telephony platform..."
  • FreeSWITCH has been used with OpenSim in the MOSES project.
  • FreeSWITCH is currently used in CybaLOUNGE, a web-world.


  • Mumble "is an open source, low-latency, high quality voice chat software primarily intended for use while gaming."
