you need a pbx system. something like Asterisk or another provider. Once you have the settings just log into the IP on the phone and fill it out. extension/user/pass. and then it will work.

These are VOIP phones which mean they work over high speed internet. You need a service provider. I have 6 phones and use Ringcentral as my service provider. Hope this helps!

I have the same problem with a 4 phone system (KX-TGA931T). Shopping for new ones too.

This is all you need. Phone & answering machine in one. Expandable too. You can add extra handsets later if you need to.

Yes you can add one of them. The base can handle 6 lines so you can add one more and I think the 410B is the same one I use to have and I added one. You have to follow the instruction how to do it but it was easy. You will LOVE LOVE the new phone if you use the bluetooth that connects your cells phones to it. Otherwise the new phone is pretty much the same as the 410B phone set. tim

The base unit plugs into an electrical outlet and also plugs into the telephone outlet on your wall. The extra handsets (I have 3) each plug into an electrical outlet. You only need 1 phone jack. (for the base unit) The extra handsets do not need a phone jack (only an electrical plug)

I just want to add my interest for additional handsets as well. The product as-is is great but we need at least 2 handsets.

You will have to buy a longer extension, you can also put multiple extensions on at one time.

Same as previous answer. I started with the base unit and 2 additional phones. It was simple to pair up and now I have added 3 more phones for a total of 5 plus the base unit.

I don't know which phones are compatible with the range extender, When I bought my phone system, Amazon was able to suggest the right one.

They all share an extension, however, on that line you can have up to 3 calls going at once, between the base and 2 handsets (assuming you have 2).

I think you can purchase extra handsets directly through Panasonic. I replaced a defective unit through them.

This is just a handset. You would have to have the main phone first, then this would be an additional extension. It won't work standing alone.

You will need a second cable that is appropriate for your phone. With this cable you can extend the headset to your phone.

The system comes equipped to support 16 X16 telephones and 4 outside lines. You can buy an expansion card to add two more outside lines for a total of six.

No u only need one and make sure your phone carrier will work on the phone.

I also bought the KX-TG9382T with which I use 5 extension phones model "KXTGA950B". I'm sorry it only handles 5. It is a good product and additionally can be paired with multiple cell phones which then ring through all the Panasonic phones if your cell phone is not near by. Absolutely no regrets for me with this equipment.

As long as you have the same model of phones, you can use this as a replacement. I originally bought a 4-handset set, and bought this one to go with it, giving us 5-handsets total. They are all identical, and work great together, and in fact, I can't tell which came with the set, and which one I bought separate.
