of the configuration parameters that you configure to make the features work.
This brief section describes the conventions used in the summary table and configuration
parameter table. In order to read the tables and successfully perform configuration changes, an
understanding of these conventions is necessary.
Summary Table Format
The following summary table indicates three provisioning methods (central provisioning, web
user interface and phone user interface, refer to Provisioning Methods for more information)
you can use to configure a feature. Note that the types of provisioning methods available for
each feature will vary; not every feature uses all these three methods.
The central provisioning method requires you to configure parameters located in CFG format
configuration files that Yealink provides. For more information on configuration files, refer to
Configuration Files on page 138. As shown below, the table specifies the configuration file
name and the corresponding parameters. That is, the <MAC>.cfg file contains the
account.X.auto_answer parameter, and the <y0000000000xx>.cfg file contains the
feature.auto_answer_delay parameter.
The web user interface method requires you to configure features by navigating to the
specified link. This navigation URL can help you quickly locate the webpage where you can
configure the feature.
