This service enables you to carry on a phone conversation with two different people, in two totally different places, at the same time and allowing you to drop off the call at any time leaving the other two parties connected.
- At any time during your call to the first person, briefly press and release the switch hook (the "hang up button") to get a stutter dial tone to call the other person.
- When the second person answers, briefly press it again and all three of you will be on the line together when you are ready to drop of the call simply hang up.
