Model 53i IP Phone User Guide 133
Available Features Enabled by Administrators
Customizable Callers List Key
Your System Administrator can specify an XML URI that creates a custom Callers
List application for your phone. When you press the Callers List key, the phone
accesses a custom XML URI Callers List instead of the standard Callers List. Contact
your System Administrator for more information.
Autodial (Hotline and Warmline)
Your System Administrator can configure an autodial feature on your phone. If
autodial is enabled, the phone automatically dials a preconfigured number whenever
it is off-hook. Depending on the configuration specified by your Administrator, the
Autodial functions as either a “hotline”, or as a “warmline,” as follows:
• Hotline: The IP phone immediately dials a preconfigured number when you
lift the handset.
• Warmline: The IP phone waits for a specified amount of time after you lift the
handset before dialing a preconfigured number. If you do not dial a number
within the time allotted, then the IP phone begins to dial the number.
The Autodial feature is available on a global or per-line basis. Contact your System
Administrator for more information.
Centralized Conferencing
The 53i supports centralized conferencing for Sylantro and Broadsoft servers. This
feature provides centralized conferencing on the SIP server (versus localized, on the
phone). Your System Administrator must enable this feature on your phone before
you can use centralized conferencing.
Centralized Conferencing allows you to perform the following:
• 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, a user at extension 2005 could create 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.
• Disconnect from an active conference call while allowing the other callers to
remain connected.
• Add unlimited number of users to a conference (dependent on the limitations
of the server).
• Join two active calls together into a conference.
• Join incoming or outgoing active calls to any existing conference.
Reference
For more information about using Centralized Conferencing, see "Centralized
Conferencing (for Sylantro and Broadsoft Servers)" on page 90.
Notes:
1. Any speeddial numbers that you configure on your IP phone are not
affected by autodial settings.
2. If Autodial is configured on your phone, any lines that function as hotlines
do not accept conference calls, transferred calls, and/or intercom calls.
