Is this a stand-alone phone or does it need to be used with a phone system?

It must be used with an existing Uniden base system. It works with the D1780 and may work with others. Buy the base system first; this is just an add-on handset.

this is a stand-alone unit. It has a connection for power and a network connection. It is configurable as a generic SIP device on the phone system that I have. If you are looking for just an extra handset I think you need to look elsewhere.

None required. System powers through the phone line. I have 5 at my shop and just bought a system for my Church. Great system!

Yes--the phone has the function but it needs to be established with your phone service.

This is an IP phone, and generally you need a hardware (PBX) and software system to serve as the backbone to run it. It's really not for use in a home -- it's a business/office device for a VOIP phone system.

This is a handset for Panasonic KXTG9542B or similar main station and has to be used only with it. This handset can not be used as a stand alone phone as it has no self connection to a phone line.

Only if your local phone company supplies it. The phone will work with the system.

You need a base phone too. I made the mistake of ordering this phone and then had to order the base so get the base first. It comes with phones. Yes it does do call waiting.

It is wall mountable with included bracket. No, this is not a phone system, only a stand alone phone/answer machine.

The previous answer is correct. This is not a sophisticated phone system. It's just a quality cordless phone with a "slave phone". You can hook up an answering machine as you would a conventional phone.

You need the base phone in order for this system to work. It does have call waiting.

I guess it depends on the definition of "system". It's not a phone and needs to connect to one to work, but it's everything in the picture (headset, charging base, cord and various ear pad/head band things to wear it with).

The phone will work as a telephone. The caller ID and answering functions need the power cord. Also the ring without the external power is different. I just tested the phone with and without the power cord to check this answer.

This one is stand alone, its a peaker phone and microphone unit combined. Un less somebody is talking at more that 3 meters away, this device will pick the conversation and relay. I personally feel whole purpose of device is to have clutter free table without mirco-phones..

You don't *need* to use the phone feature. It's optional. But it does need a landline. Cell phones will not work.

it is just a holder, you would need a separate remote. But we just use the phone's timer :)

No. This is a simple bare bones phone. It's sounds great and I got it because I didn't want a phone with any additional electronics or anything else to plug in.
