  • Press the Conf soft key
  • Add your second party by either:
    1. Pressing a hotline key or dialing an internal extension to add an internal party
    2. Dial 9 plus an outside telephone number to add an outside party.

To continue to additional parties to the conference call:
  • Press the Add soft key
  • Add your next party by either:
    1. Pressing a hotline key or dialing an internal extension to add an internal party
    2. Dial 9 plus an outside telephone number to add an outside party.
  • Once you are done adding parties to the conference call and are ready to tie everyone together on the same call, press the Begin soft key.
  • As long as one party from internal phone system remains on the conference call, anyone can drop off and the call will remain intact.
