By default, the phone automatically selects a bandwidth setting that balances the audio and video network
requirements.
You can configure a fixed bandwidth setting to override the automatic selection, if required for your 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.
