Does your call block computer support a whitelist?

In a sense, it can. You have to manually enter those phone numbers you will accept calls from.

Yes you can block calls and up to 250 phone numbers. You can have it block calls that no phone number is attached to like "Private Caller" I find this a life saver after having around 100 blocked numbers so far but there are always more coming in but I've really cut the nuisance calls dramatically. Great feature to have and blocking calls are very easy to do.

Yes it will block them. I have not had this problem myself but I went to Digitone's Website that said that this is illegal but what they call "Spoofing Services" are using them (Notice where it says Digitone Call Blocker adheres to these requirements or will be Blocked): "According to BellCore Publication TR-NWT-000031M, Issue 4, December 1992, it states as a Requirement that: All calling line Directory Number (DN) shall be transmitted in Calling Number Delivery (CND) to the Customer Premises Equipment (telephones) in a 10 digit format. As of late, this network protocol is being completely ignored by internet spoofing of a number. Since the internet is not policed by the FCC, this leaves spoofing open to whoever wishes to employ those spoofing services. However, the Digitone Call Blocker adheres to these requirements and compels the calling number received to fit within these 1992 guidelines or be blocked. The DCB Plus will also allow 11 digit numbers like 1 602 555 1212 to ring through as "1" is the long distance country code for the USA. Other country codes before the 10 digit number base also ring through as valid numbers."

Since you have to input each phone number separately, I don't believe you can just block a certain area code.

Yes it does. I ended up get a new phone that had an option to block calls built in. Much easier to program.

There are ways around the blocker, as an example someone could use Skype to get an unlimited amount of numbers to call you from in different area codes. However the blocker will also let you create a white list of accepted callers and block all other phone calls. I ended up having to go that route to keep someone from harassing my family.

Yes, you can enter numbers, area codes and prefixes manually. You can also wait for unwanted calls to ring and then press the BLACKLIST button to add them to the Blocked list. You can do that while the calls are ringing OR afterwards by browsing the list of incoming calls (stores the 100 most recent numbers). The BLACKLIST memory stores up to 1,500 numbers and 10 area codes.

Not automatically. You can block any number by selecting the caller list and saving the number to call block. First, use your phone to turn on blocking on anonymous calls with your phone company,. Star( *) 77 usually works and you will get a three beep acknowledgement from the phone company when you turn it on. I wrote an article about call blocking today.

Dear Nancy,We have had the Digitone Call Blocker for about a year. I has cut down on annoying call of all types and IT DOES WORK!! It will block unlisted and private numbers that come in as unknown name/number and will indicate to you where the call came from. At this point you can BLOCK or INVITE the call. If we don't know who it is they are blocked. You can block entire area codes also. My suggestion to you is to visit their website. Any and all questions are answered there. If not call them direct they are GREAT to talk with, I did. It is the only workable and worthwhile investment. Easy to install and the instructions are easy to understand. Read my Post on Amazon.

I have that set up exactly, and it works well. Once in a while it will block a wanted call, but I find that if I call them back, the next time works fine. I can only guess at the cause. I've got the blocker on the phone at the farthest point from the modem, and it works.

Gary,If your phone caller ID now says "blocked call" or "unavailable" this device has nothing to remember to block.It must have some numbers to put into its memory. It will block 000-000-0000 political callers! I proved that!

Yes. When a call is received, the unit rings for a short time while the caller is being identified. If the phone number matches an entry in the call block list, the unit sends out a busy tone to the caller, and then disconnects the call. You can store up to 30 phone numbers in the call block list by using the caller list or by entering the numbers directly. You can also block unlimited calls with no number such as Out of Area and Private Number.

Yes, but some still come through. If callers conceal their number, it won't ring. But, if a valid number calls, even if the name is blocked, it will ring. Still, you can individually block any specific number, so a harassing caller can be kicked out, a satisfying tool indeed.

I had the same problem and corrected by changing the block anonymous calls to true via the web interface. Refer to the administrator's guide page 111.

If you have caller id service from your phone company, you probably have a feature you can enable called Anonymous Call Rejection. That feature will block any call that does not have a number associated with it. Then any call that comes through would have a number unless it is an "out of area" call. The T Lock, problems not withstanding, can block any number you put on the blacklist. Be aware of the following: Caller ID blocking ONLY WORKS FROM RESIDENCE TO RESIDENCE. Commercial users can retrieve your number with an ANI box even if you block your caller id. I got that surprise one day when a business I called for price and availability on a local number with my caller id blocked, called me back on my number to tell me that they found what I was looking for. What a shock and an education I got.

Call blocking is not a phone specific feature, it is a service provided by your phone company (Verizon, AT&T;, VOIP,etc.).You can also register your phone number with https://www.donotcall.gov/ to help revent unwanted or unsolicited calls.To answer your question, NO phone is independently capable of blocking calls, only the network provider offers this option.

Yes, you do. The call blocker uses the caller ID to identify calls to reject or pass. Some call blockers use black listing to reject specific numbers. Some call blockers use white listing to pass only those numbers you wish to receive calls from. Some can do one or the other. Those that use white listing do a better job of blocking undesirable calls, but can sometimes be a pain when trying to receive calls from the doctor's office or the school. Probably more than you were interested in.
