Conference Call Feature on Desktop Phones (Audio Only)

UC Irvine's Analog phone system (Ericsson), Digital phone system (Ericsson, Aastra, Mitel), and IP phone system (Mitel) have a built-in conference call feature. For a telephone conference of up to 16 parties, this may the best and most economical choice.

  • Ericsson, Aastra and Mitel Phones - 3 - 8 participants (including up to 6 off-campus)
  • No Web conference feature
  • The only costs are long distance or toll charges for connections initiated by the host to off-campus participants.  If all parties call in to the UCI phone, the call would be free of charge.
