We have a panasonic kx-t7431 phone system in our office and want to add 2 more handsets to it. How do we do it

Hello,

Each phone needs it's own set of wires to the main control unit. You cannot use splitters or connect a new jack up to another jack like home phones can. Do not connect your phone directly to the phone company's phone line. It will not work and a ring signal will break your phone.

The phone you have (kx-t7431) can work on one of several different Panasonic phone systems so your first step is finding out which model control unit you have.

Some of the smaller systems you can plug phones directly into them but the larger systems need a phone jack terminated at a punch down block.

Once connected your phone should work with the default settings. If you need it to ring at special times or with special phone lines then you'll have to do some system programming.

If you want to tackle this yourself you will probably need to obtain an "installation & programming" manual for your specific system.
