Procurement and administration of conference call accounts for Columbia's faculty, staff and administrators

Also known as dial-in, audio conferencing, conference bridge, conference line or teleconference line.

CUIT's Voice and Mobile team offers AT&T conference call accounts for Columbia University staff who need to accommodate multiple parties or need to lead a group call from a mobile or standard telephone. AT&T conference call accounts can support a maximum of 125 participants. If additional participants are needed for AT&T, CUIT must be notified in the initial request. For costs and charges, please contact the CUIT Billing department.

  • Open the conference call 10 - 15 minutes prior to the actual set time of the meeting.
  • Remind all participants that side/background noise can be heard by all on the call.
  • Ask all participants to mute their phones when on hold or not actively participating.
  • The conference will start when the host opens the call with their password.
  • The conference will end when the host hangs up or logs out.
  • Please do not put your line on hold if your phone has hold music.
  • Speakerphones may cause noise during your meeting. Please mute your microphone when not speaking.
  • To minimize disruptions caused by hold music, speakerphones and other background noise, the Mute feature allows participants to mute their line. To use the Mute feature, the participant should press pound then zero (# 0) on their phone. A menu will instruct the participant to press 1 to mute their line and then they will rejoin the conference. To deactivate the mute feature, the Participant should press pound then zero (# 0). The menu will prompt the participant to press 1 to return to talk mode and they will rejoin the conference. Note: Tones will be heard as participants perform these functions.
  • At least one participant must dial in (and remain on the call) within 30 minutes of the scheduled start time or the conference will be terminated and a No Show Fee will apply.
  • If you take a break longer than 15 minutes, ensure you leave one line connected to the conference to prevent the conference being terminated.

At any time during the call, the host can press the following key combination to achieve the features listed below.
