No, I wouldn't think so. Basically when the call you want blocked comes in, simply press the "Call Block" button and confirm that you want that number blocked. The phone system will place it on a block list that is internal to the phone. If that number attempts to call you in the future, it will ring once and the phone will promptly display a "Call Blocked" message.
Sorry, there was a problem. Please try again later.You need Caller ID. Call block stores the caller's number in a list and does a lookup on the list when a call is received. If the number's in the list the call is blocked.
