Even though your setup uses all microphones during a call, not all speakers
are used. Depending on the call, either your phone's speaker is used, or the
Polycom HDX or Polycom RealPresence Group system's speakers are used.
Speakers are used in the following ways:
• Video-only calls use the Polycom HDX or Polycom RealPresence Group
system's speakers only.
• Audio-only calls use the SoundStation IP 7000 speaker only.
• Adding video to an audio-only call switches from the phone's speaker to
the Polycom HDX or Polycom RealPresence Group system's speakers as
soon as the video call connects.
Adding audio to a video call continues to use the Polycom HDX or
Polycom RealPresence Group system's speakers. The Polycom HDX or
Polycom RealPresence Group system speakers are used as long as there is one
video participant.
