Choose one of the following options: Answer call, go to 1a. Reject call, go to 1b. Silence the incoming call alert, go to 1c.
When you reject a call, the caller will hear a busy signal or be diverted to your voicemail.
Tap the upper or lower part of the Volume key when you get a call. The incoming call alert is silenced. If you take no further action, the call continues until the caller disconnects or the call is diverted to your voicemail.
You can silence the incoming call alert if you don't want to answer or reject the call right away. Afterwards, you can still answer or reject the call.
