•Encrypt when possible — Endpoints supporting 
encryption join encrypted; others join unencrypted.

encrypted; others can’t join.

encryption settings of On and Off. If an RMX running an 
older version is selected for a conference, the settings 
Encrypt when possible or Encrypt all are both converted 
to On.
