Line Keys and Programmable Keys

Conference Key

By default, the 53i has a Conference key configured on Key 6. However, using the
Aastra Web UI, you can assign the Conference key to another available key if
required (Key 3 through Key 6).
The Conference key allows you to link three active calls into a single conference
(Local 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.

For more information about Local and Centralized Conferencing, see "Conferencing
