Making Conference Calls

Conference calls can be held among 6 users of the university’s VoIP (Voice over Internet Protocol) phones to facilitate doing business.

Conference calls can be held between multiple users of the university’s VoIP (Voice over Internet Protocol) phones to facilitate doing business.

Any VoIP phone user can initiate a conference call. The limit is 6 participants, including the initiator. Only the person who initiated the conference call can add more participants, unless they transfer control to someone else. The conference call will not end when the initiator hangs up if they are using a VoIP phone.

Adding Callers to a Conference Call

  1. While on a call, press the More soft key and then the Confrn soft key.
  2. Dial the second party’s number. When the party answers, press the Confrn soft key again. Repeat to establish up to six callers.

To transfer control of a conference call to another participant, press the Transfer soft key on your phone's screen while the conference call is ongoing, dial the number to which you would like to give control of the call, and press Transfer again.

Joining Existing Calls into a Conference

The Join feature allows two or more existing calls to be combined to create a conference call.

  1. From an active call, highlight and select the call you want to include in the conference.
  2. Press the Select soft key.
  3. Press the Join soft key.
  4. Repeat this step until all calls are joined to the conference.

Handling Incoming Calls

An incoming call answered on the same phone line that an active conference call was initiated from will appear on the phone’s display. If the incoming call is answered, the initiating phone will be automatically placed on hold; however, all other conference call participants will still be able to speak . If the call is not answered, the call will go to voicemail.

To add an incoming call to a conference call on the phone that initiated the conference call, press the Answer soft key and then select the Join soft key (a check mark icon will appear next to the incoming call). Navigate to and highlight the conference call and select the Join soft key again. The call will now be a part of the conference call.

Long Distance and International Phone Numbers

Conference calls can be made to long distance and international numbers if phones are configured with those options. Long distance dialing to North America is the default configuration. International calling options are based on departmental needs. Long distance and international dialing configurations are established by departments.

You can initiate virtual conferences, instant message, make audio and video calls, and hold online meetings using Microsoft Lync instead. 


Conference call participants do not hear music when the call is put on hold.

To avoid disturbing others in a conference call if you need to leave the room temporarily, press the Mute button on the front of your phone to prevent others from hearing any sound from it. You will still be able to hear other participants while you are muted. Press Mute again to unmute.
