The new iPhone operating system includes a feature to send all unwanted calls directly to the voicemail. This eliminates the daily car warranty spam calls. If someone calls you from a number that is in your contact list, in your recent outgoing call list, or in a Siri suggestion, the call rings your phone, otherwise it is immediately forwarded to the voicemail. If it was an important call, the caller can leave a message and you can call them back.
