Description
Specifies dynamic feature
set discovery.
Value operation:
• 1: The phone discovers
and verifies if the
controller supports the
AST feature set or not.
The phone sends a
SUBSCRIBE request to
the active controller for
the Feature Status Event
Package (avaya-cm-
feature-status). If the
request succeeds, the
phone proceeds with
PPM Synchronization. If
the request is rejected,
or is proxied back to the
phone, or does not
receive a response, the
phone assumes that
AST features are not
available.
• 0: The phone operates
in a mode where AST
features are not
available.
Note:
Set the parameter to
0 for an Open SIP
environment.
Specifies that the display
name will be used for the
remote party if the server
supports a phone
providing its own display
name.
This parameter is used
only in 3PCC environment.
Parameter values must
not include the following
symbols: ";<>/&.
