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.

This device is very effective screening out unwanted callers, particularly that most annoying of all callers, "UNAVAILABLE". Since one can block by number or NAME, we were easily able to block ALL calls identified as UNAVAILABLE by the single press of a single button.

Seems to be working well. The directions were difficult to understand. I Googled them and found videos that helped with the setup. It definitely helped reduce our SPAM calls. I am still getting used to how to add spam callers to the device. Overall, it seems to be helping.

Calla are blocked (I think), but the display sometimes makes no sense. "List is empty" when it is not, unreadable characters, no "number blocked" confirmation. Call Blocker 2 was great so I thought this would be better. The return window closed after only one month so I'm stuck with it.

Understand, I've only had it for two days, but so far it's working perfectly. We were getting aproximately 20 spam phone calls a day from a hydra spam entity called "Spam Risk" which uses thousands of different numbers. After installing the spam blocker the first call we got was of course, Spam Risk. I simply pressed the red block name button and it confirmed the block. After that, blessed silence. So far we have NOT gotten any more Spam Risk calls, while ALL of the regular calls go through. This is a BIG win for us. Digitone has our gratitude for making a good product that actually does what they say it does.

Buy this. Set it up. It works!

It said it would work with Ooma but it did not. It was able to block and unblock a call, but kept seeing what it thought was call with random numbers that were not really there. We just have the basic service that does not provide blocking.

Pros: I bought this because it can block calls based on Name in addition to Number, to catch robo-callers using rotating numbers. It has a large number of configuration options. After installing this unit I stopped getting SPAM calls. Cons: After a few weeks I realized that I was not getting ANY calls. I called our landline from my cellphone and saw that the Digitone was displaying garbage characters (gibberish as another commenter here says) instead of the correct caller ID. Further testing revealed that this was true of all incoming calls. I reset the unit to default settings (Reset DPS3 User Settings Code 99#*) and caller ID functionality was restored. We'll see how long that lasts. The user interface needs improvement, i.e. an optional web interface. It's difficult to grasp all the different settings, options, lists, and filters through the unit's tiny LCD display. The documentation requires serious effort to decipher. If you read the section "New Processing Levels", you could easily be led to believe that your designated VIP numbers will always ring through, but that is not necessarily the case due to how processing order works. In summary, this device can be very effective for those willing to invest time in understanding and maintaining its configuration.

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.
