Handling Call Termination Screens on the Phone UI
The following procedure describes how to handle the call terminated screens on your phone.
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.
Configuring Centralized Conferencing Using the Configuration Files
You use the following parameters to configure centralized conferencing in the configuration files:
Global Parameter
• sip centralized conf
Per-Line Parameter

for the global setting to work on soft lines, the user must configure the lines with the applicable phone number.
