Configuring three-party conference
The device offers two three-party conference configuration methods:
• Subscribers configure the function by pressing keys on a telephone.
• The system administrator configures the function through CLI on the device.
Configuration prerequisites
• Install an FXS voice card on the device
• Install a voice processing module (VPM) on the main board of the device
• Enable the call hold function in the voice subscriber line of the conference control device
Enabling three-party conference by using keys
The device supports configuring the three-party conference function of the FXS voice subscriber line
through a telephone.
The three-party conference configuration performed on a telephone also takes effect on the device. For
example, after you configure three-party conference through a telephone, and then execute the display
this command in the corresponding subscriber line, you can see the corresponding operation results.
The three-party conference function depends on the call hold function. Therefore, you need to enable the
call hold function before configuring three-party conference.
Enabling the three-party conference service in voice subscriber line view will invalidate the local call
identification function (if configured). For more information about the configuration of the local call
identification function, see the distinguish-localtalk command in Voice Command Reference.
