The landline phone system we had in our home worked fine however the problem was that we were constantly bombarded each day with Robo Calls and all kinds advertising and junk spam phone call that were just never ending and very annoying to say the least. I did quite a bit of research on Amazon on the new generation of phones that included anti spam technology and ultimately decided up this Panasonic phone system after going through all the product reviews. I also liked the fact that it was made by Panasonic. The phone system I was replacing was also Panasonic and had served us well for many years so I have faith in the brand. Setup and installation of the system was straight forward and easy enough and within 30 minutes I had the system up and running and set up. I did have to read the instructions in order to set up my preferred preferences (voice message, ring volume, spam settings, etc) but I found the instructions very clear and easy to follow. This phone allows you to sync it with your cellular phones, which is a really nice option, but I have no interest in this feature at the present time so I didn't bother with that, however I did read the instructions on how to do it and it didn't appear to be to complicated. I may utilize the cell phone feature later.. I found the system to be visually attractive and of quality construction and the best part of all is that from the minute I activated the system the spam phone calls immediately stopped. It was like a miracle We would receive no less that a dozen such annoying spam phone calls each day, sometimes two dozen. It's been 2 days now and we have not received even 1 such annoying call. My wife and I are thrilled to say the least and if a spam call does slip through somehow all we have to do is simply press the "Block" call button and the phone and that number will never be able to call us again. The system comes pre-programmed with an internal list of known spam callers and you can add your own numbers to that list if you need to simply by hitting the "Block" button. Doesn't get any easier than that. This is really a great system, I love it. Its spam blocking technology really works well and the amount of other features that the phone has is amazing. If you're looking to replace your older phone system in order to avoid those annoying spam calls just order this system.... you will be very happy you did.
