Caller Blocking
You can block incoming calls from specified Caller IDs by adding them to your Black List. A maximum of 30 Caller ID
numbers can be defined as Blocked. The blocked keyset caller does not hear any tone and the call is immediately
disconnected. The blocked SIP caller hears a busy tone. To learn more about adding numbers to your Black List, see
Using the Address Book Options on page 33.
