Using a Programmable Button
The Conference Meet Me button feature can be used to create a programmable button to join a personal meet–me or system conferences. The button can also be used to transfer other caller’s into a conference.
If the button is configured with a specific conference ID, the button also shows the status of the conference.
If the button is configured without a conference ID, when pressed the user is prompted to enter the required conference ID.
This option is not supported on J139 and non-Avaya phones.
