Does this phone need a main control to work as part of a system or do the phones work as stand alone?

It has to have a "brain" which is what I call it. It is a system they all connect to.

We have a system that has more than 20 phones to it, and we have a company that we call each time we need something done. I think it is a very complicated system. The only thing we are doing ourselves is purchasing the new or replacement phones. Hope this helps!

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

I have this telephone downstairs with the handset it came with. Upstairs I have an auxiliary handset that operates off the telephone downstairs. Saved me installing telephone line upstairs and it works perfectly.

I can only agree with Scott, these handsets are a pain. They would loose the connection to the base and lock up, and then you have to reset them by taking the battery out. We had 2 handsets and 4 main units and finally got rid of them. There are systems out there that work a lot better and are reliable.

In my experience, each phone needs to be programmed separately. If you hear of a way to do it, please email me

Yes. It is essential since there is always some hardware issue with these phones.

I faced this need and satisfied it by buying a complete new system with the answering part, then I used only the hand sets. I think I found a source for the handsets, and it was cheaper to buy the complete set and use only the new handsets. If you buy additional handsets, I found you had to cancel all the current handsets and then re link the old as well as the new handsets. Worked fine doing that.

I agree with the above 2 answers; also I've integrated 2 TG77 systems where I engage maximum 6 allowed on one system - mainly downstairs; the other for additional separate system upstairs using 3. Very happy with the phones. Just purchased a system for my sister's house too.

It does allow for App remote control and if you have the unit plugged into your Home Network via the Ethernet interface then no secondary wireless adapter is required. The phone will need to be on your Home Wireless and then this unit plugged into either the WiFi Router via the Ethernet cable or into a switch that is plugged into your home WiFi router.

I haven't used the dual sim card feature yet. My guess is if you have a 2nd sim card (for a different carrier says in a different country) you can switch between the 2 sim cards when needed. Standby probably refers to how long the battery lasts when you're not using the phone. I'm reading on my phone so I frequently has it hooked up to charge. I would say if you don't use it you could have it standby for a couple days. For such a large phone, it doesn't drain the battery that quick, pretty decent.

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.

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

nope. System uses cellphone technology, completely separate from your other connected gizmos

it can operate stand alone and syncs with phone device when it finds it available....

I believe this phone only works with the matching control unit, and would not be usable without it.

The phones themselves are digital and you need the processor unit make them operate. You would need to buy a second processor unit to divide the phones up between two locations.

I have three phones in our home on one number also, and my unit is installed at the "entry point' because I wanted all phones to be on the same system. My understanding of the instructions indicates this is the proper method of setup
