the channel hear the call simultaneously.
You can join pre-configured channels. Public channels are
open to anyone who knows the URL for the channel.

joined to the channel hear you talking. Up to five channels
can be active at the same time.

channel for the first time, you must first create the group or
channel. Select Options > Add existing , and enter the

is ready when the first participant answers.
