Summary: complete, capable, cool
Review: The Siemens 2420 is fantastic! The desk station has a great speakerphone (great sound quality without all that annoying background "I'm on a speakerphone" white noise), answering machine, and other useful features (mute/hold/conference).The handsets let you do almost anything remotely (call transfer, hold, intercom, switch lines, etc). Additionally, the handset chargers can be plugged in anywhere, so you don't have to deal with phone lines except for the base station, so it's easy to spread the handsets out all over your home/office where they're needed. The range is great and the sound quality is top notch. About my only complaint about this system is the wireless handsets only do hold, not mute. (this is actually an incredibly minor point, and I can't think of other handsets that have it either)

Summary: Wish the handsets worked as well as the base
Review: I bought this system for my office after I had installed a 2415 at my home. I was in the honeymoon period at home and decided that we needed the same at the office. Initally everything was as good as advertised. The receptionist (who loved the features) thought she was in heaven and life was good.
Then the handsets started failing, one after the other. Eventually, like my handsets at home, they all failed- every single one. Siemens was very distant and unhelpful, although they replaced the handsets the replacements failed more rapidly (I suspect they were "factory reconditioned") After the warranty was up, Siemens would only offer to sell me more handsets.
Now the base, whose LCD screen no longer works, sits on a side table. People use it to make outside calls and answer pages. They comment on the styling (I agree with that), and remark on the sound quality (quite good on the base). They ask what the antenna is for, and I tell them not to ask.... they don't want to know.

Summary: High Cost for Poor Quality Product! Don't Buy Siemens
Review: I bought the 2420 with desk station and handset. First thing to fail was the handset where the display and then the number 4 on the keypad gave out. This of course was just after the warranty period ended. Next the desk station LCD display stopped working and there is no way to repair it. Without the display working there is no way to program the phone. I need to be able to turn off the answering machine mode (because I use Vonage voicemail) and cannot do it. There is no flow chart in the manual that would show me the button pushing steps to accompish what I need to do. So I am throwing this expensive piece of sh*t away. I will never buy a Siemens telecom product again. The default on the phone is answering machine on, so there is no way to reset it (unplug it) and have the answering maching function turn off.

Summary: DItto; opened up handset - disturbing gell found
Review: Ok, so our handsets have been getting flaky.
the buttons stopped working.
I opened it up.
There is some odd clear sticky gel everywhere, and the circuit board is discolored.
this is not battery goop, either. this is something else. I suspect either whatever was in the rubbery buttons OR whatever was in the contact layer for the switches.
I am now shopping for a replacement. I do need the dual line, multiple handset features, and would like some kind of battery backup. any advise?

Summary: Garbled sound, piece of junk, avoid Siemens
Review: This phone is junk. I spent way too much money buying handsets and base units. Sound is garbled on handsets. Range is minimal. Base unit disconnects callers. Tech support completely useless. I wouldn't buy anything from this company.

Summary: Great, when it works
Review: This is a great phone system. 2 lines, up to 8 handsets, voice mail, intercom, conference calls, etc, etc. So why 1 star? When it breaks, you're SOL. I've had my system for 4 years. Had a few minor problems, Siemens tech support helped, replacing a defective handset in the first few months. I was happy. All of a sudden, 3 months ago, all the handsets started having intermittent problems where the sound was garbled, in a digital sort of way (no static, just parts of conversation coming in and out a few times per second). I contacted Siemens, and their response was "mechanical problem with handsets, we won't fix it, buy new ones". Huh? Mechanical problems, like you get when you drop a handset? But this problem started on all handsets, at once, and is intermittent. Doesn't sound like a mechanical problem, in the handsets or the base. More likely it is a problem with the firmware in the base unit. Talking a bit more to Siemens, I find that I can't just buy a new (8825) base unit, because the handsets I have aren't compatible. Great - so I have two choices: 1. Buy a refurbished base ($130), and perhaps get the same problem 6 months from now, 'cause the firmware is likely the same, and Siemens will continue to insist the problem is a mechanical problem in the handsets. In 6 months, tech support for 2420 will probably be worse than it is now, and if refurbed units aren't available, I'm SOL. 2. Buy a new base and handsets ($500). Since Siemens hasn't even admitted a fault with their 2420, how can I have confidence that they fixed the problems with the 8825? And if there is a problem, I'll get the same lousy support and incompatibility once the 16300 (successor to 8825 - just guessing on the number) comes out. I picked door #3. Goodbye.

Summary: Desk Station hangs up on callers.....
Review: I bought a Siemens 2420 desk station and 2 handsets. Everything worked great in the beginning. Within a year the desk station stopped working altogether. I took it back to Office Depot where I purchased it because I had purchased a warranty. They replaced it. Soon afterwards the cordless units would not hold a charge, nor
did they hold a charge after I purchased the exact duplicate batteries. Then the desk station would shut down on the second ring of an incoming call. All the buttons would light up red and the LCD display would be all blocked out on the second ring. It would then reset itself and repeat the process on the next incoming call. Siemens technical support HAS NO authorized or unauthorized service/repair centers. They suggested I take the phone to my local electronics repair shop.......or buy a new one. Yeah right. I would definetely NOT purchase another Siemens product.

Summary: Defective LCDs
Review: I originally purchased a 2415 a few years ago, but for some reason it was not compatible with Verizon Caller ID. Siemens thought they were doing me a favor by upgrading me to the 2420. They weren't. I didn't need the 2 line feature, but I did like thephone and the other features. It would be a good system, but for one major problem. The LCDs on these phones are prone to failure. Without a readable LCD, you cannot use many of the phone's features. I replaced the original phone after about 2 years with a refurbished model I bought off eBay, because the LCD on the first phone became totally unreadable. Now after about 2 more years the replacement phone's LCD is failing.
