The Conference Key allows you to link active calls into a single conference (Server-Side Conferencing). This key also helps to create multiple conferences with unlimited participants on your phone if your System Administrator has enabled Centralized Conferencing on your phone.

Note: You must set the maximum number of conference participants on your conference server.

Reference

For more information about Server-Side and Centralized Conferencing, see “Conferencing Calls” on page 57.
