Audio and ringtone settings

Audio settings live under Me → Settings → Audio.

Ringtone

Pick a built-in ringtone or use your phone's default. You can set different tones for internal vs external calls.

Echo cancellation and noise suppression

Both are on by default. Turn them off only if you're troubleshooting one-way audio — switching them off rarely improves anything.

Audio codec preference

By default the app uses Opus on Wi-Fi and G.722 on cellular. Force a different preference only if your administrator asks you to.
