On Team Number, you may notice that you're asked to "Press 1 to answer the call, or Decline it to send it straight to voicemail". This is to help your calls route properly to the correct device amongst multiple team members.
If you've accidentally invited someone to join your team or you're currently the only member on your Team (recently removed someone), you can toggle the Call Announcement setting at anytime so that you're not required to press 1 when answering a call.
If you have a member other than yourself under Team Number, the Call Announcement feature will not have the option to be toggled on/off.
If you have any questions regarding Call Announcement, please let us know :)
