Control the Video Bandwidth
If you have a busy network or have limited network resources, users may complain about video issues; for
example, the video may lag or suddenly stop.
By default, the phone automatically selects a bandwidth setting that balances the audio and video network

conditions. If you configure a fixed bandwidth, select a setting and adjust downwards until there is no video
lag.
Procedure
Step 1 On the phone web page, select Admin Login > Voice > Phone .
Step 2 In the Video Configuration section, choose a bandwidth from the Bandwidth Allowance list to restrict the

Configuration, on page 245 and Video Transmit Resolution Setup, on page 43 .
Step 3 Click Submit All Changes .
Adjust the Camera Exposure
You can adjust the camera exposure for the ambient light in your office. Adjust the exposure to change the
brightness of the transmitted video.
Your users can also adjust the exposure on the phone from Applications > User Preference > Video
