Sound

Open Settings, then Devices.

• Microphone is what the other person hears.
• Speaker / headphones is what you hear during the call. Pick the headset by name if you use one.
• Ring device is where the ringtone plays. It can be a different device from the call speaker, such as a TV or room speakers.
• Ringtone file is a WAV file. Browse to it. If the box is empty, SipWarp uses its built-in ring.
• Local DTMF plays a tone when you press a keypad button.

The Mic and Spk sliders work during a call. 100 is normal. It does not make a quiet microphone louder than the headset already is. Move the slider down to make that side quieter. Mute silences it.

The ring slider is saved. It does not change how loud the ringtone is.

A quiet voice is usually the headset or the Windows volume for that microphone, not a missing switch in SipWarp.
