Centralized Conferencing (for Sylantro and Broadsoft Servers)
The 6753i allows you to create multiple conferences with unlimited participants (depending on 
your server limitations) when your Administrator enables Centralized Conferencing. 
If your Administrator does not enable Centralized Conferencing, then the 6753i uses Local 
Conferencing by default.
Your Administrator can configure Centralized Conferencing globally on all lines or on specific 
lines. Although, for the global setting to work, you must configure the lines with the applicable 
phone number.
Note: You can use 2 and 5 to scroll through and see the numbers and names (if 
available) of the parties in the conference call. When a name is displayed, 
pressing 4 drops the displayed party from the call.
