Three-way-calling allows the Subscriber to have a phone conversation with two different people in to different locations at the same time.
To do this make a call to one of the two persons that you wish on the three way call.
Once you have that call connected, ask the person to hold and press the flash button. You will hear three beeps and then dial tone will return and you can call the second person that you wish to talk to. Once this call is in place press the flash button once more and all three of you will be on the call at that point.
