Simultaneous Interpreting

@RuiZhang1 - When you are setting up the meeting, you can define all of the different interpretation channels that you want in the meeting settings. 

Once you start the meeting, if interpretation is turned on, you will see a Globe icon at the bottom of the host's screen. 

If you click on that, you will get the Manage interpretation screen.

If you select the Add Interpreter button, you will get the option to add an additional interpreter.  Keep clicking on Add interpreter to add additional interpreters.
