MSUM Telephone Three-way Calling Instructions

Three-way calling instructions for analog phones enable a person on an existing call to add a third party to the connection.

To add third party to your conversation:

  1. Depress switchhook once to get dial tone.
  2. Listen for dial tone.
  3. Dial number for third party.
  4. When called party answers, depress switchhook once. Three-way call is established.

Important Reminders Regarding Three-Way Calling:

  1. Upon completion of a three-way call, it is necessary for the person who initiated the call to depress the switchhook twice—once to restore the station with the original call and second to disconnect the consulted party. If this is not done, the consulted party is not able to receive or initiate a call for approximately eleven seconds. An attempt to initiate a call before this time interval reconnects the consulted party with the existing call.
  2. On a three-way call, if the third party disconnects, the call will continue. It is necessary, however, for the controlling station (station user who initiated the three-way call) to depress the switchhook once to disconnect the third party. If this is not done, the third party is not able to receive or initiate a call for approximately eleven seconds. An attempt to initiate a call before this time interval reconnects the third party with the existing call.
  3. On a three-way call, if the second party disconnects, the call will continue. However, the second party is not able to receive or initiate a call for approximately eleven seconds. An attempt to initiate a call before this time interval reconnects the second party with the existing call.
