Well guys, the same as the others, noteworthy, I won't elaborate,
more to help the others with the review,
I got an extra headset PANASONIC KX-TG2511 BLACK and connected it easily, there are instructions in the base manual. From what I saw in the process, I believe that many others can be connected as well, I'm just mentioning which one I tried.

The telephone system was worth its money. Now I am trying to find two more headsets to expand the coverage network because the space is large. I suggest buying if you manage to get all the headsets you need from the beginning because now I am struggling to find them. It takes up to six.

I was looking for a call blocking program and the reviews for them were not good.
I am very satisfied with this Panasonic phone, as it cuts off all harmful calls just by entering the first digits of the scam numbers. I finally have peace and tranquility, and there is also a "do not disturb" function - no calls in the middle of the night except for the numbers you have entered in the phone.
Very very satisfied with this device

Excellent package has it all: quality, answering machine, intercom, and many more. Panasonic guarantee.

We have spent a lot of money on phones, but this time we hit the jackpot!!!! The best phone we have ever bought!!!!! It's worth it, don't regret the money, you just won't need to buy again for many years!!!!

Well, the phone is great and really worth buying. It includes a transformer from the same company, but if it breaks, you can go to a store that has Panasonic spare parts and it costs around 10 euros. The device also takes batteries that you have to buy separately for the cordless device, which are not included in the package. The phone works with batteries alone, but when they run out, it is dead because it simply needs the transformer and it is needed in case of a power outage, for example. The phone is perfect and the separate cordless device can be plugged into any socket without the need for a telephone line. It has many melodies compared to the landline phone, which only has one. The mobile device has rechargeable batteries included in the package. Another great feature is the answering machine, which you can set to mute on any phone if it repeatedly bothers you. The screen is illuminated on both devices. Don't even think about it, though, because it's worth its money.

It is an expensive phone, but it is worth its money. It has amazing features that are extremely helpful, such as muting incoming calls and putting them on the answering machine, intercom, call waiting, and generally a 60-page manual that you will enjoy exploring. If it also had a built-in PBX to have a welcome message, it would be the ultimate office phone. I recommend it for a small office or for a home where the position is not convenient due to the router or line installation. However, compared to the SNOM D715 that I have in the office, it is better and has an amazing menu in Greek. I recommend it!

Quite a quality construction. For an office with 2 employees and 1 closed office space, it saves you from the process of buying a telephone center.
It is a recent purchase and it is a phone that if you have the appetite and deal with it, it becomes better and better. I will come back after some period of use.

Perfect for a small business with a receptionist position. You avoid the need for a call center: it has internal communication, call forwarding from one phone to another, and voicemail.

I haven't had it for a long time, but so far, everything looks good. I was impressed that the wireless only needs power and not a telephone cable. In theory, this means that in a new installation, you need much less meters of telephone cable. The wireless device fell once from a height of one meter, maybe a little more. It didn't suffer any damage. It shows good and durable construction.

I have them for 2.5 months and I am completely satisfied. Quality construction with many features. The essence is that you don't stay without a phone in case of a power outage. The wireless device has long-lasting batteries. It also has a hands-free headphone jack.

Very good and user-friendly device, good range on the wireless headset when you need to move a few meters away from the base, excellent sound quality and plenty of additional options for anyone who wants communication between the 2 devices, and switching between 2 callers when you have 2 incoming calls simultaneously.

Practical, with the existing data you never stay without a phone, thanks to the Buckup batteries that are not included in the package.
