Call Stats
If voice quality is poor during a call, you can tap call stats key to view the current status of the
call to find out why.
Codec, bandwidth, total packet lost and other parameters about presentation are included in
the call stats. For example, when a delay occurs or the video has a ‘mosaic’ look, you can view
the total packet loss to check whether the packet has been lost.
Before configuring a call stats key, you should enable the video conferencing feature (refer to
Video Conferencing) first.
