Connecting to a Conference
Direct Dial-in
Direct dial-in connection to conferences and Meeting Rooms is available
to all endpoints.
Participants must be provided with a dialing string which can vary
according to the network type, conference password and chairperson
password.
Participants dial the conference dial-in string and are connected to the
conference IVR Service. Once the correct information, such as the
conference password and chairperson password are entered, the
participants are connected to the conference.

The MCU can be configured to enable the chairperson to use the
chairperson password as the conference password without the need to
enter the conference password.
