Private channel — Only persons which receive an invitation by the channel
creator can join in.
Provisioned channel — A permanent channel is created by the service provider.
You can set the status of each channel to Active or Inactive.
The number of active channels and the number of members per channel is
limited. Contact your service provider for details.
