When you reject a call, the caller will hear a busy signal or be diverted to your voicemail.
Tap the Top or the Bottom volume key when you get a call. The incoming call alert is silenced. If you take no further action after silencing the incoming call alert, 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.
