Handling Calls
Centralized Conferencing (for Sylantro and Broadsoft Servers)
The 55i 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 55i uses
Loca 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.
Reference
For more information on Centralized Conferencing, see "Centralized Conferencing"
on page172 or contact your System Administrator.
