Three-way calling service allows you to arrange events or chat with friends and family by talking with two different people in different locations at the same time - no matter who placed the call.

To Add a Third Person:

Depress the hookswitch or link button to put your call on hold.
Listen for three tones followed by dial tone.
Dial the number of the third person. When he/she answers, you may talk privately before adding your first party to the conversation. Depress the hookswitch or link button and release to establish a Three Way Call. (If you receive a no answer or a busy signal depress the hookswitch or link button twice to return to your first call.)
To disconnect, have either of the people hang up and you can continue a two-way call.
 

Highlights:

If you hang up the other two people will be disconnected.
You may use Three-Way Calling to add another person after someone calls you.
When the Three-Way Call includes long distance, you pay only for the call you make.
Call Waiting does not work during a Three-Way Call.
