Question

How do you set up a three way call?

Answer 1

While on a call put the party on hold briefly by pressing the Link or Flash button. Listen for three short beeps followed by regular dial tone. Press *71.

Dial the number of the second party you wish to call. When the person answers, press the Link or Flash button to connect

all three parties immediately.

If the number of the second party is busy or does not answer,

press the Link or Flash button twice to return to the original call.

Answer 2

for mobile devices or landline?? for mobile devices, ex: tmobile, it is already included...for landlines you have to check what bundle you have from ur provider and see if it is included...att charges you a leg an arm for it, just get a handset---you are way better off...2 yrs go by fast.
