Three-way calling allows you to add a third party to a previously established connection. If either party hangs up after the three-way call is established, you are still connected to the remaining party.

• To initiate 3-way calling, first establish or receive a call with one party, then depress and release the hook-switch to put the original party on hold. Listen for three bursts of dial tone followed by steady (normal) dial tone.
• Dial the number of the third party. When this party answers you can talk privately. When you are ready to establish the conference connection, depress and release the hook-switch.
• When the originating party hangs up, all parties are disconnected and the call is completed.

If the third party does not answer or the line is busy, depress and release the hook-switch and you are connected to your original party.
