Three-way calling allows you to talk to two different people at the same time. With three-way calling, conducting business or arranging personal meetings is easier than making several separate phone calls. If you have a Panasonic cordless phone, making three-way calls is easy to do and can be done in a matter of seconds.
Contact your phone company and make sure you are subscribed to a three-way calling service.
Make a phone call, and connect to one of your desired contacts.
Press the "end" button to put the contact on hold, and then turn the handset back on.
Wait to head a series of fast beeps. Dial the third party you would like to add to the call.
Once connected to the third party, press the "end" button on the receiver again to add the original person you called. Both callers should be on the line.
