Do one of the following:
- Pick up the handset.
- Press the Speaker button.
- If you are using a headset, press the main button on the headset or press the Headset button on the phone.
If your headset is not plugged in when you press the Headset button, you won’t be able to hear the call because the audio is going to the headset port, but the call is still active. To recover the call, press the Speaker button, or pick up the handset and press the Headset button again.
