??????? ??????? ????????? ???! I did have to read the manual front to back to completely to set up the phones exactly as I wanted. It really is important to read the manual to correctly set up everything. I do have a land line so I plugged in all of the phones to charge and connected the base to the regular land line. Following the instructions, I connected it to my Samsung Galaxy Note II cell phone. Then over the next week, I was pleasantly surprised with the quality and many features of the Panasonic wireless telephone set.????: The Link-to-Cell feature is fantastic! With the cell phone connected, you can place calls using either the cell or land line and designate which you prefer to use as a default. Also, you do not need a land line to use this phone set. It will connect up to two cell phones via blue tooth. The cordless handsets ring normally when a call comes in via land line or cell phone. The handsets also show caller ID and whether the call is from the land line or cell. The handsets will also announce who the call is from for voice calls and even when you receive text messages on the cell number. The calls are clean, clear and I can not tell without looking to see which line is being used. A separate ringtone can be selected for the cell line to let you know if you desire. The base is complete with a full number pad and is also a speaker phone. Setting one handset sets all of them as far as time/date/phone book, etc. I was able to download every name & number from my cell phone to the handsets in a matter of a few minutes. The cell phone also automatically reconnects when I get back home from errands without any prompting. I have not tried it yet, but a blue tooth headset can also be connected at the same time as two cell phones and the land line. I will update if I try that feature.???? ??????? ??? ??: Call blocking. This handset can block 250 different numbers. On "junk" calls, the phones "never" ring and show "Call Blocked" on all of the handsets. I receive "junk" calls all of the time for extended car warranties and so many other useless things. I block the numbers the first time and have been very pleasantly surprised how nice it is to eat dinner without having to listen to the phones ringing or answer "junk" calls!????: If there is a power failure, the base handset must be in the base because the base relies on the handset for backup power. One improvement I can think of would be for Panasonic to put batteries in the base also just in case of power failure. I do have the unit plugged into my computer UPS just in case of power failure so I do not have to worry about that. Lastly, it would be nice if the volume level could be increased a bit for the hard of hearing as the volume seems lower than a few other brands.???????: I do not believe there is a better digital cordless handset telephone on the market at this time! I highly recommend this telephone package. I will be suggesting this package to anyone wanting the best out of a phone system.
