How can I enable or disable CBR

Calls can use either Variable Bit Rate (VBR) or Constant Bit Rate (CBR).

When using CBR, a corresponding label will be displayed on both the calling and the receiving side. This setting only affects 1:1 calls; conference calls always use CBR encoding.

When using VBR calls use fewer data and work better on slower networks. Turn off to use constant bitrate encoding (CBR).

On desktop

To enable CBR:

1. Go to Preferences.
2. Click Audio / Video.
3. Uncheck the checkmark – Variable Bit Rate Encoding.

To disable CBR/enable VBR:

1. Go to Preferences.
2. Click Audio / Video.
3. Check the checkmark – Variable Bit Rate Encoding.

On mobile

To enable CBR:

1. Tap  to go to Settings.
2. Tap Options.
3. Toggle VBR off.

This will apply to both sides, and the whole call will use CBR.

To disable CBR/enable VBR:

1. Tap  to go to Settings.
2. Tap Options.
3. Toggle VBR on.
