The KX-TG4000B base unit and each cordless handset communicate in both directions using 2.4 GHz frequency-hopping spread spectrum (FHSS) transmission. FHSS technology improves calling range and clarity, and eliminates crosstalk. Because it rapidly changes transmission frequencies within the 2.4 GHz bandwidth, this cordless system helps reduce the possibility of eavesdropping.
The KX-TG4000B operates via cordless transmissions, so no expensive (and messy) wiring or installation is required. Simply hook up the base to your phone lines and plug it into an AC outlet. Then, set up the included KX-TGA400B handset in the desired location and plug in the recharging stand. Up to seven more optional KX-TGA400B handsets can be added to the system.
The convenient, reliable, all-digital voice mail includes many advanced features. The KX-TG4000B offers a general delivery mailbox on the base unit, plus up to eight personal mailboxes--one for each handset. Each user can record a personal greeting, and can access individual mailboxes from any system handset or an outside line. You can set the voice mail system to automatically answer all incoming calls with a recorded greeting, and to route callers to a desired extension or mailbox. The KX-TG4000B allows for four separate voice paths, so four system users can access voice mail at once.
This phone system also includes a digital duplex speakerphone with an eight-step volume control. Digital circuitry in the base unit helps reduce echo and the dropout effect for more natural-sounding conversations.
Dual caller ID with call waiting lets you view the name and number of all incoming callers on either the base unit or handset LCD--even if you're already on the line. This caller ID feature also stores up to 50 names on the base unit (up to 30 names on each handset), with direct callback capability. And thanks to caller ID pager call, you can even program the phone to notify your pager when you've received an incoming call, and to forward caller ID data to your pager's display. (Subscription to caller ID services is required.)
Other features include two-way intercom/paging, lighted handset keypad, headset jack in the handset, and a belt clip. The handset offers up to eight hours of talk time and up to 96 hours of standby battery life.

I liked the ability to have access to all the lines (including my fax line) on one system. This system has excellent functionality based upon the attendant and call routing. It also has better range in our 4,500 sf house than the Siemens 2420 system, which only is only a two line phone (more later). This system has large programmable memory locations, intuitive interfaces on the extensions as well as the base station.HOWEVER, the primary purpose for acquiring this phone was to use the base station as my primary office phone with the capability to roam throughout our three story house. As a base station, this system is severely lacking. Although the speaker phone is great, it has NO MUTE! If you participate in conference calls, you need a headset with a mute switch to have an offline discussion or even sneeze. Also, using two friends as guinea pigs, the sound quality was pitiful on two different units of this same model thinking it...Read more 33 of 34 people found the following review helpful: By A Customer This review is from: Panasonic KXTG4000B 2.4 GHz DSS 4-Line Cordless Phone with Caller ID and Voicemail (Office Product) Battery life rated at 8 hours talk time on Panasonic web site but believe me, it's closer to 2 hours. We've had to switch handsets in mid conversation more times than we should. Also, when talking on the phone, incoming calls are not put into voice mail automatically, they are ignored. Such an obvious feature overlooked (if it is possible, we can't find it explained anywhere in the manual). Also, when listening to messages, you can not save the message on the base unit, you have to transfer it to a handset/mailbox or lose it. Best feature is that you only need one phone jack for 8 handsets, you can put the handsets anywhere you want (near an electrical outlet). Handsets not very comfortable for long conversations. Overall, we wished we'd waited for shortcomings to be worked out. Lots of reasons to buy, these are some reasons to wait or look elsewhere. 63 of 70 people found the following review helpful: By Mark in Hoboken (Hoboken, New Jersey USA) - See all my reviews This review is from: Panasonic KXTG4000B 2.4 GHz DSS 4-Line Cordless Phone with Caller ID and Voicemail (Office Product) I purchased the Panasonic KX-TG4000B as a replacement for my old Siemens Gigaset 2420. I'm really disappointed with the Panasonic KX-TG4000B, and I'm considering trashing it and returning to my old Siemens Gigaset 2420.The Panasonic KX-TG4000B has some critical flaws: The problem with the "one handset per line" is basically that you CANNOT join a conversation ... you get "line busy". For example, if the base unit has a call going on line #1, and you try to join that call from one of the cordless handsets, then you get a "line busy" error message and a busy signal. So, if someone else in the house in on...Read more |
