This would have a 5 star rating if it was not for the two major problems. This system has been discontinued and is only available used, refurbished, or new (old stock) if you are extremely lucky. The KX-TG4000b 4 line base unit system with built in voice mail and capability to handle up to eight 4-line cordless handsets KX-TGA400b or cordless desk sets KX-TGA420b. You can also use the 2-line cordless handset KX-TGA200b but would be limited to the first two phone lines. The system is easy to install and program. A normal phone system requires a separate wire going from the base to each telephone. This system is completely cordless and you only need to wire up your incoming phone lines to the back of the base unit. The range of the cordless handsets is average to better than average. Also, voice mail setup can be very tricky in a standard phone system, sometimes impossible for the end user to do alone. This system does not have all the fancy options other voice mail system may have but the price for the entire system with phones is less than a typical voice mail system on a hard wired phone system. HOWEVER, there are two major flaws with the telephones. First: The keypad! With a failure rate of 100% and an average life of 6-18 months depending on usage, the keypad contacts were designed too small!! The contacts barely make contact when new and any tiny bit of dirt, gunk or buildup makes the number buttons extremely hard or impossible to use. To make matters worse, the rubber keypads seep an oily substance that quickly gums up the already fragile buttons. The harder you push, the more oil is forced out. Many rubber keypads do this but you would not notice if the contacts were of the appropriate size. Second: Choppy transmit. The RF (radio frequency) module is easily knocked out of alignment. This effects the transmit quality but not what you hear when using the phone. It starts out with the other party not hearing you well, sounding like a cheap cordless phone too far away from the base. The problem quickly worsens and soon your callers can't understand you at all. Worse, you loose the link to the base unit, calls are disconnected or your phone just does not ring in the first place. The problem also can occur in the base unit RF module but this effects what you hear in all the cordless handsets and is much easier for you to detect when using any cordless phone on the system.Read full review
The Panasonic 2-Line and 4-Line systems aren't perfect, but there is nothing else on the market that I've found that compares. Essentially, for $200-300 you can buy the base unit (on eBay, for example) and end up with a 4-line PBX with voicemail. That's simply not possible at that price for a keyswitch or PBX. It's also very simple to install and program. The kicker for our company was that we also didn't have to rewire Cat-3 all over the place, because the handsets are all wireless. The handsets themselves are large enough that you don't feel you're using a cell phone. The belt clips work, and you can plug in any standard inexpensive headset. Both the phone and the base station remember dozens of calls, report caller ID, and have excellent functionality. A lot of users have commented on problems with the keypads. Frankly, we had 14 in use and never had a keypad fail in almost 3 years. That being said, we did replace the keypads before selling them all (we switched to VOIP), at a cost of about $9 apiece, which seems reasonable as the used handsets regularly sell in the $100-140 range. Unless you switch to a VOIP-based PBX (such as Packet-8, which is what we use), I think the second-best (and less expensive) option is the Panasonic system -- particularly for small offices with 2 to 8 employees.Read full review
I bought the KX TGA400B Cordless Expansion Handset a few weeks ago and was in need for an existing KX TG-4000B Base unit currently in operation at a small business office. Two handsets are existing and this will be the added one. The number of features available on this phone is what is attractive and very reliable. I've had this in service for over 2 years with daily operation of receiving/sending calls of more than 30 per day without any downtime in phone functionality. Four persons in our office with 3 lines can rely on these phones. Overall, I'd recommend the phone and the phone system if you're needing reliability and value priced in commercial grade equipment.
A great 4 line cordless phone. Very durable. The phone has good range too. The phone will go at least 100 feet from the base through walls. There is one little hitch. The #1 fails on these phones. That's ok, replacement keypads are cheap. You can find them on ebay. One word of caution. Don't buy the keypad from the guy in New Hampshire. His add is misleading and all he sends you is a membrane he claims is a "keypad." It doesn't work either. You actually have to have the rubber keypad to make the repair. Buy from the guy in California. You get the rubber keypad and the membrane (which usually doesn't fail) for 20 cents more than just the membrane the NH guy sells.
I bought this phone because we have the system for our office. It is very easy to add phones as we grow. We have the base and four cordless handsets. This is one phone that Panasonic would do well to manufacture again. So far getting more phones and service has not been difficult. The key pad needs to be replaced after a lot of use as #1 wears out. The phone has all kinds of features and handles business needs easily.
