Siemens S450 DECT 6.0 Digital Cordless Phone System

 (19 customer reviews)

I purchased this phone and 3 additional S45 handsets approx 2 months ago and every phone has performed flawlessly. Before buying the system I read reviews of numerous phones, went to stores to hold the handsets of many of the phones, and reviewed the literature on the manufacturers' websites. In the end, I bought this phone with the belief that it would probably have issues, but I could always return it to Amazon if it did. Needless to say, the only complaint is from my wife who initially complained that the phones were so robust that it was difficult to figure them out -- while this may seem true, think of these phones as a close relation to a cell phone.

Regarding the complaints I have read; let me address the following ones:

1. ISSUE: It is impossible to switch from 1 call to another with call waiting -- you have to hang up on the existing caller. SOLUTION: Simple, depress the "Flash" button on the lower left corner of the phone and easily switch between 1...Read more

First of all, I don't understand the person that gave this 1 star. I have tried and returned every other phone I ever bought. But this phone is engineered beautifully. The sound quality on both receive and send is crystal clear. DECT is fantastic because it doesn't interfere with any other wireless frequencies. This is a total full function phone and is even VoIP capable(with an additional module) if you want that. It's expandable with other handsets(I'm about to order one of those). The reception at long distances from the base is also excellent. Now, if you like big huge buttons and heavy phones, this phone is not for you. But if you like modern, stylish, full featured phones with excellent sound quality, etc, then get this. Btw I don't work for Siemens, nor am I affiliated with them in any way, I just like this phone better than anything I've tried, and believe me I've done a lot of research on phones. I've done much more research than I should have had to do because there...Read more

I bought this unit, plus two extension units and was plagued by digital stuttering, both listening to people at the other end, and what they were hearing when I spoke. It ranged from annoying millisecond dropouts to several second dropouts of all audio. At the time, we were staying with friends during our house remodel, and this unit was connected to their Comcast digital cable modem telephone port. I thought the phones were the problem, so I sent them back to Amazon for replacement. Then my friends bought the same units and had the same problem. They sent them back and got the Panasonic version of the DECT 6 phones. Lo and behold, the Panasonic had the same problem. A knowledgeable acquaintance advised that there was likely some sort of packet-switching interference between the digital signal of DECT 6, and the digital telephony of cable operator provided systems. Sure enough, when we got back into our house (with an analog phone line), these units performed flawlessly over long...Read more
