A 3-way call can be done while on a current call.
To start a 3-way call:
- Place the current call on hold.
- Select New Call, and dial the number.
- After the 2nd call connects, press Conf.
If disconnecting just one party is desired on a 3-way call, that party will need to hang up. Otherwise, end the current 3-way call by hanging up, then call back the desired party.
