How to Place Conference Calls with Mitel

by Darryl Brooks

Conference calling with a Mitel telephone is a straightforward process. Like many functions with these phones, it uses what they call a feature code. Depending on your phone setup, this feature code may be programmed into a button and labeled Conference. If not, you will need to know the feature code for this function, which is 5.

If you don't have a Mitel user guide, get one from your telephone administrator or contact a Mitel rep. These are invaluable to operating the many functions available on these telephones.

Locate the conference button on your phone. If you don't have one, locate the feature key which looks like an infinity symbol. Place a call to the first person you want to conference as you normally would. It doesn't matter whether this is an internal extension or an external number.

Press the conference button. If you don't have one press the feature key followed by a 5. This will place the first caller on hold.

Place a call to the second person you want to conference. Press the conference button or feature code combination to place the second caller on hold. Repeat these steps as often as needed to get all callers on the conference call.

Press the conference button or feature code combination a final time to join all parties on the call.
