Centralized Conferencing (for Sylantro and Broadsoft Servers)
The IP phones include support for centralized conferencing (Ad-Hoc conferencing) for Sylantro
and Broadsoft servers. This feature provides centralized conferencing on the SIP server (versus
localized, on the phone) and allows IP phone users to do these tasks:
• Conference two active calls together into a conference call.
• When on an active conference call, invite another party into the call.
• Create simultaneous conference calls on the same IP phone (Sylantro servers only). For
example, the IP phone user at extension 2005 could create these two conferences, and put one
conference on hold while conversing with the other party:
— Line 1: conference together extensions 2005, 2010, and 2020.
— Line 2: conference together extensions 2005, 2011 and 2021.
When an IP phone user is connected to multiple conference calls, some outbound proxies have
maximum call “hold” time set from 30-90 seconds. After this time, the call that is on hold is
disconnected.
• Disconnect from an active conference call while allowing the other callers to remain
connected.
• Ability to create N-way conference.
• Join two active calls together into a conference call.
• Incoming or outgoing active call can join any of the existing conferences.
If the administrator does not configure centralized conferencing, then the IP phone uses localized
conferencing by default.
An Administrator can configure centralized conferencing on a global or per-line basis using the
configuration files or the Aastra Web UI.
To use the centralized conferencing after it is enabled, see your Model-specific IP Phone User
Guide .
Note:
When you configure centralized conferencing globally for an IP
Phone, the global settings apply to all lines. Although, for the global
setting to work on soft lines, the user must configure the lines with the
applicable phone number.
