What happens when my phone is streaming music to the Commuter and a call comes in?

When a call comes in, the audio on the Commuter will pause, and the call will ring through the speaker.

If you wish to answer the call through the Commuter, simply press the circle button on the control panel to answer the call.

You can now talk into the speaker itself to conduct your phone call.

Once you end your call, music playback will resume. Some details of this experience will vary depending on the implementation by the phone manufacturer.
