Hi Gustavo,
According to the Resource Center article linked below, if you have either the Admin or Telephony Admin role enabled, you can turn auto-answer on or off.

If you don't have those permissions, depending upon your contact center's setup, you might be able to ask your Telephony Admin if that can be changed for you.
I hope this helps.
Thank you,
Clay
