A slow flashing red lamp on an appearance button indicates an alerting call. This may also be accompanied by ringing and by the message lamp flashing.

To answer the call on a headset, press the HEADSET key.
Just pressing the alerting appearance key answers the call either on the speaker or headset depending on the phone's default audio path setting. See Default Handsfree Audio Path.
To switch to using the handset, lift the handset.
To switch to handsfree, press the SPEAKER key. If you were using the handset you, can now safely replace it.
To switch to headset mode, press the HEADSET key. If you were using the handset, you can now safely replace it.
If you have answered the call on the speaker or headset, pressing the SPEAKER or HEADSET key again before you select another mode ends the call.
Just pressing the call appearance key or any other appearance button puts the current call on hold.
