Digitone ProSeries 3 Call Blocker Automatic SPAM Blocking for Landline Phones - Easy Setup One Button Blocking of RoboCalls

Been using this since Oct '25. I had one of the older model big red button ones for several years which worked pretty well for its specs until it began hanging up the phone after two rings regardless of who was calling (I found out after I threw it out after its years of faithful service there's a workaround for this when it starts doing it). Anyway, the new big red button model I purchased in Sept '25 to replace it unfortunately has newer version software/hardware which causes it to be incompatible with my setup - thus I returned it. Then I got this Digitone to see what it'd do. Works great and is very effective. . Also shows (and you can block by) caller name which big red button doesn't do. This is especially satisfying as it can block city names which spammers use - this cut down the nuisance calls considerably. Many options/variables can be simply programmed and the instruction manual isn't too bad if you have your brain engaged. One heads up for those using a landline phone to remotely access their automated driveway gates: this blocker blocks a visitor’s call from the gate and, in addition, will not allow remote operation from the phone the blocker is attached to. An extension phone elsewhere on the same landline can control the gate remotely but it doesn’t get a visitor’s call, either. Excellent technical service (in the USA) at Digitone suggested I try a couple of codes hopefully guessing they might work, but they sadly didn't as the issue is really gate-related. As an aside, my old model big red button did not interfere with the gate operation but their new model does. As the current version of big red button and Digitone's both interfere with the gate operation, I’m choosing to use the Digitone as the name blocking function is great. My gate controller is a 20 year old Chamberlain/Sentex Crown Jewel and I can’t say if this issue effects any other makes/models.

It works!!! I have VOIP and I am so happy to have nuisance calls blocked. It works the way it's supposed to and it's simple to use. The instructions could be better written, but that is my only complaint.

The unit basically works, but I have two issues. The first is with the product, which is supposed to be able to terminate a call and block the number with the touch of a button. That basic function simply does not work on my unit and I don't know why. I can later go back into the call history and manually block the number, but the instructions clearly state that I shouldn't have to do that. The second issue is with the seller who provides a single means of contact. An answering machine with no greeting and no acknowledgment to the customer that the message has even been received. It seems pretty Mickey Mouse for an American company with a very respectable product line. ( I also got no callback on my call for help). There is no chat, no customer support email address, or even a user forum to turn to. Frustrating.

I bought this for my mother, she has a landline and is getting robo calls from Medicare. This did not stop them. I am returning it.

I bought this device as I had an obnoxious caller calling about 20 times a day from an "800" number that kept changing every time. But the caller kept showing up as "800 Service" all the time, so I was going to use the block by name function to block this caller. I did a fair amount of research and decided this was the best device with a lot of options for blocking unwanted callers. Funny thing, the day I got the device is the day that these calls just stopped. So, I put the device in a drawer and will have it ready next time I am in this situation.

I bought this because of the never ending cavalcade of robocallers, scams, etc. I was seeing anywhere from 10 to as many as 50 calls in a day. The weekends would see the count drift lower, but not completely stop. First, this was NOT a plug and play and then I was protected setup. You should expect to do some setup. But once I had it set properly, it became a rare thing for one of those unwanted calls to get through. The unit just sits and quietly ignores the calls I don't want, and passes through the calls I want. Specifically, I had to add known good exchanges to the allow list. I also added people with numbers from exchanges that are not local. Then I set the DigiTone to block or reject all calls that are not explicitly on the allow list. And the method I chose it to just let the call ring indefinitely. Another option is to have the DigiTone answer the call and then hang up. I decided this latter method was not the best choice, as having anything answer the call indicates the number is alive and active. One note: Pay attention to the phone number of allowed callers. I was missing the leading 1, the country code for USA. Once I added the 1 plus the allowed call numbers and exchanges, the unit worked as expected. Even the samples in the book do not show the 1 as part of the numbers. Without that 1, the DigiTone did not recognize my allowed numbers. Pay attention to how the numbers are displayed in the caller ID. That's it. Once the allow list was setup, the DigiTone started ignoring the relentless calls and my phone only rings when I have a legitimate call. Again, a very slim few did manage to get through, But there have been so few of those I can count them on one hand, without exaggeration. In short, I recommend this and would buy another if needed.

I have had my phone blocker for about a year and it worked well till now. It will not block calls every time. Also, since it is digital, I think a hacker may be trying to do hack it. It was lit up like it was being used, but I had not had a call all afternoon.

What a brilliant device . . . I had about 20 numbers that I’d written down of SPAM callers, which were very easy to enter into the system, and instead of the usual 20-per-morning SPAM calls I’ve been getting, I haven’t had one, since plugging this in. Best money ever spent.

Let's get real about our modern world. Ingenious telephone scammers are now a fact of life, just like rainy days are a fact of life. For those with a landline, managing this modern reality is mandatory for peace of mind. An effective call blocker is a good way to do this. I've tried a few. My experience is that inexpensive call blockers which solely depend on algorithms to block spammers are simply too problematic. Their algorithms always block legitimate calls and allow spammers. I was looking for a device where the algorithm could be over-ridden by the user to allow legitimate calls, something most inexpensive blockers simply do not do. However the Digitone device's algorithm can be overridden and the user can customize both white-lists and black-lists. But be warned: it's complex to do. While the Digitone device only works on a landline (not a smartphone), it is an effective call blocker. Nonetheless, if there were ever a product where one needs to be told RTFM, this would be that product. The Amazon website barely scratches the surface of the blocker's many features (likely Amazon's website has bandwidth considerations). So I went to the Digitone website with my many questions. At that website I found the admonition to DL and read the pdf manual to understand what the blocker actually can do. But could I find said manual? Eventually I did, but it ain't easy. Hey Digitone, redesign your website. The pdf manual is a bloody pain to find, although once found it's easy to DL. Instead, make the manual easy to find. The thoroughness of the manual was what sold me on this multi-featured call blocker. It was after reading the manual three times that I came to realize this call blocker would do exactly what I wanted. DOS weenies take note: wildcards can be used to block or allow large sets of phone numbers and even area codes. The good news here is because this is a US company the manual is written in standard comprehensible English (but no other language). My lone phone call to the company's support line to clarify a couple minor points was handled quickly and completely by someone who could speak fluent US English. But again, fair warning. Even with a good manual and good support, this blocker is still quite complicated to use. A person better be very comfortable with intricate technology to use this device successfully. For the record, the blocker doesn't get all the scam phone calls. Nobody's invented that device yet, nor is anyone likely to do so in the next few years. Spammers are not only clever but insidious. This blocker just gets most of them. But understand this: it's the customizations which the *USER* does which govern how effective this blocker is. That's why RTFM is the mantra here. As thorough as the manual is, if one has a VOIP phone (as I do), know that the manual is weak on VOIP advice. Be prepared to fiddle around with series and parallel phone hookups (Google the difference) until you find the one that works for your setup. The manual's advice to always use a serial configuration was flat-out wrong for my VOIP phone setup. By trial and error I found a complex mix of serial and parallel configurations work best for me. Someone else's VOIP phone may well differ. Those with a traditional Ma Bell landline likely won't have this issue. FWIW the manual seems to be written for the more common POTS phone. So do I still get spam calls? Yes, a few. But I consider a 95% reduction in spam calls to be well worth the extra bucks this blocker costs. After all in the end you do get what you pay for. The cheap blockers are just that: cheap. And I don't mind the required customizing of this blocker that I have to do. If I have to invest a bit of time and creative thinking to make effective white- and black-lists to over-ride the Digitone's algorithm, it's time well spent.

A GREAT investment. We were getting up to a dozen scam calls everyday. It took me a while to figure out the best programming for the device but, now that I have, ZERO scam calls. Worth every penny!

The call blocker may or may not do as the manual says. It may reset for no apparent reason. It may lose a setting. A feature that worked before no longer works. Tech support may or may not hang up on you. The product and the people both need more refinement.
