Add a third party to the conversation while using only one phone line.

To add a third party:

  • First, to hold your existing call, depress the "switchhook" for about a second.

  • Then dial the third number, (speed calling codes may be used if you also have this feature).

  • When the third party answers, you may talk privately before completing your three-way connection.

  • With your third party on the line, depress the "switchhook" for a second to add the holding party. Your three-way call is now in effect.

  • If for some reason the call to the third party is not completed, depress the "switchhook" twice to get back to your held party.

To disconnect the third party:

  • Depress the "switchhook" for about a second. You will now have only the original party on the line.

To disconnect completely:

  • Simply hang up.

  • If either of the other two parties hangs up, you can continue to talk to the one remaining.


The “switchhook” is the round, flat, or square button you push to hang up the phone.
