Does the AI Receptionist block spam and robocalls?

Yes. Spam filter is set to “Screen likely robocalls” by default: callers the carrier can't verify, hidden numbers and rapid redials hear “press 1 to be connected”. People press 1; robocalls hang up. “Block likely spam” is stricter and also refuses numbers that fail the carrier's caller-ID check, so a real caller could occasionally be asked to press 1. You can also turn it off.

In the same place you can list Blocked numbers (they hear a busy tone) and VIP numbers, which always ring you and are never screened. Spam calls show up in your call log marked Spam, and they never become leads or get a text-back.
