Call Feature Codes

If an individual attempts to place a local call beginning with the two digits in the special feature access codes listed above without first dialing a 9, the special feature is activated. It is necessary to use new 3-character codes to access the special features of the switching facilities. The use of the new codes will prevent the accidental activation/deactivation of the features. The new codes use the current numbers preceded by an * (asterisk). The new codes are as follows:

Conference Calls

Conference calling is one of the many features supported by the MSU phone system.   Conference calls may include up to 8 people including the initiator (person following these instructions).  To initiate a conference call, follow the instructions below.

  1. Dial the first party and announce the conference call.  Ask that party to hold.   D-Term phone users depress the TRF key on their phone and dial 3521.  Let it ring twice and hang up or depress recall.  Standard phone users depress the hook-switch, dial 3521, let it ring twice, and hang up.
  2. Repeat step one for each party.  A total of 8 parties may be included in the conference call.
  3. When all of the parties have been included in the conference call, dial 5005 to include yourself in the conversation and to make sure that all parties have been connected.
  4. To insure privacy, D-Term phone users located in the I & T building dial 0.   D-Term phone users located elsewhere on-campus dial 00.  Standard phone users dial 0.

If only three parties need to be on the conference call, try Three-Way Calling instead.

If you have any questions or comments please call the Telecommunications Office at 6801.
