Adjust Audio Quality

If calls on the Cloud Voice App sound unclear, you can tune a handful of audio settings to sharpen them. The controls cover echo removal, the audio codec, network optimization, and volume gain.

Open the audio settings

1. On the Calls page, tap your account name in the top-left corner.
2. Go to Settings > Audio Options.

Available settings

Adjust any of the following to suit your environment.

Setting	What it does
Echo Cancellation	Turn this on to strip out the echo you sometimes hear while talking on the phone.
Codec	Choose the codec (coder-decoder) used to compress your audio. It uses lossy compression to keep quality high while shrinking the amount of data sent. Options are u-law, a-law, iLBC, G722, G729 (default), and Opus.
ICE (Interactive Connectivity Establishment)	Turn this on to reduce network latency and packet loss for a steadier connection.
Audio Gain Control	Raise or lower the level of the audio you receive and the audio you transmit. Useful when the other party sounds too loud or too faint.

Tip

Change one setting at a time and place a test call after each change. That way you can tell which adjustment actually helped.

Note

Changes to the ICE setting only apply after you close and relaunch the Cloud Voice App.
