Have had unit for more than a year. Mainly for 2 remotes for picking up when not in home office and calling voice mail from cell for messages.

As others say, would like listening volume to be higher but have had no complaints on outgoing.

One of my remote units seems to be deaf after one-year. All functions work, battery shows full charge but no sound can be heard - no mute isn't on. UPDATE: After reading so many reviews on how customer service was so useless and reading manual and all the FAQ's on the Panasonic site with nothing related to my "deaf" unit, I ordered another from AMAZON. BUT just then thinking to give it a chance just before Panasonic Customer Service closed I called. Helpful person with good English had me take out the battery, wait 1 minute to reset the unit. Vola! I can hear again.

Went back to cancel order on Amazon like 30 minutes after placed and was too late already being prepared and have to get it and return it. Can't blame Amazon for being so fast!

I hate the voice mail retrieval asking me if want English or Spanish. I live in the U.S. not Mexico. I don't know a word of Spanish. It is annoying that question can not be turned off to avoid the extra selection step. The U.S. language is ENGLISH! So why do I have to put up with the needless step?

This is my second 4-Line Expandable Cordless Phone System of Panasonic. This one is a bit different from the TG4000B I had. It has a better and clearer sound. It has more features if you have the time to read the thick booklet you can find many more. It is a plug and speak system that is delivering what you basically want: a clever home-small office telephone system without all the bother of wiring every room or station. It is a Panasonic product which means you should not have any issues with quality. don't hesitate.

I've been working with this phone system for several months now, and I like it very much. We have a smaller office-based business with only two lines and one remote handset, but for what we paid, its a great phone.

It looks like most of the negative comments are from customers familiar with the previous 4-line Panasonic phones. I guess if you're used to them, this one has some continuity problems. I'm sorry about that, but for a first time user, the phone is very good.

We don't use the pager feature, or the automated attendant. I have recorded our own music, and discovered its very important your music has virtually no bass at all. (That's why so many voice mail systems have light concerto violin music, due to the lack of bass.) If there's any bass, it will distort badly. (Not Panasonic's problem, but a limitation of the phone line audio dynamics.)

The voice mail system works well, but it plays exclusively from the speaker phone on the base unit, even if you have a headset plugged in. That's not so great if you're wanting to preserve privacy and anonymity. In fact, depending on your circumstances, it might make this phone completely unacceptable because of this. Why Panasonic didn't modify this feature, I don't know. Major oversight, if you ask me.

However, the unit does have a headset for the base, and a headset can be plugged into any of the handsets. This is almost unheard of for this kind of phone. Its really excellent, and the call quality is outstanding using a good quality headset. (I use an older ATT model, with adjustable volume, and it works great.) I also have a wireless GN Netcom headset that isn't as loud, and customers don't hear me as well on that one.

The menu system is fairly easy to navigate. There are a bunch of features packed into this phone, and I've spent a lot of time with the manual to make sure I have very clear understanding on how the system works. So often, frustration develops when you assume you understand how something works, only to find out it has a different operation than you're used to.

The intercom/transfer pad is a bit confusing, (case in point.) I thought it was a quick dial pad, when its not. Its an intercom/transfer system... just like it says. (Duh.) So, all the quick dial names are currently whited out.

Its a fairly complete phone. It may not have all the features you're looking for, and might be very frustrating if you're used to an older Panasonic model, but for the average small office, its great, and highly professional. (We got ours as a demo unit for half price, so that's also a big part of our satisfaction.)

We recently set up a base unit with 3 cordless handsets. Setup was simple, and the basic systemn works well. We're still learning all the bells and whistles.

We bought this system when it was released. It beeps on your line when a phone call comes in on another line and steps on your conversation having you to ask the person on the other end of line to repeat what they said. After finally being fed up with this design flaw I called for tech support. The unit has been updated to overcome this issue, but they won't update the software for you. Also, if you use this system in a business (who won't?) you have to send yours in first and wait 7-10 days. Phone support is horrid.
