18.5.2 Configuring Supplementary Services
The Supplementary Services page is used to configure parameters associated with
supplementary services. For a description of the parameters appearing on this page, see
'Configuration Parameters Reference' on page 541.
The procedure below describes how to access the Supplementary Services page and
configure the supplementary services parameters. In addition to this, you can also refer to
the following specific services configuration:
Call hold and retrieve - see 'Call Hold and Retrieve' on page 293
BRI suspend-resume - see BRI Suspend and Resume on page 295
Consultation - see Consultation Feature on page 295
Call transfer - see 'Call Transfer' on page 296
Call forward - see 'Call Forward' on page 298
Call waiting - see Call Waiting on page 300
Message waiting indication (MWI)- see 'Message Waiting Indication' on page 301
Caller ID - see Caller ID on page 303
Three-way conferencing - see Three-Way Conferencing on page 305
Emergency 911 calls - see Emergency E911 Phone Number Services on page 306
Multilevel Precedence and Preemption (MLPP) - see 'Multilevel Precedence and

Notes:
• All call participants must support the specific supplementary service that
is used.
• When working with certain application servers (such as BroadSoft’s
BroadWorks) in client server mode (the application server controls all
supplementary services and keypad features by itself), the device's
supplementary services must be disabled.
