A conference call may involve participants with video conferencing systems
and participants with speakerphone systems. In some embodiments, sound
from speakerphone participants may be sent through a speakerphone sound
system while sound from video participants may be sent through the video
sound system (e.g., near a video monitor). Sound may be localized through
a combination of both the video sound system and the speakerphone sound
system to produce a spatially correct sound field for in room
participants.
