Yealink SIP-T48G Administrator's Guide

Administrator’s Guide for SIP-T2 Series/T19(P) E2/T4 Series/CP860 IP Phones
44
IP phones can be configured automatically through configuration files stored on a
central provisioning server, manually via phone user interface or web user interface, or
by a combination of the automatic and manual methods.
The recommended method for configuring IP phones is automatically through a central
provisioning server. If a central provisioning server is not available, the manual method
will allow changes to most features.
The following sections describe how to configure IP phones using each method.
 Phone User Interface
 Web User Interface
 Configuration Files
An administrator or a user can configure and use IP phones via phone user interface.
Access to specific features is restricted to the administrator. The default password is
“admin“ (case-sensitive). Not all features are available on phone user interface. For
more information, refer to Yealink phone-specific user guide .
An administrator or a user can configure IP phones via web user interface. The default
user name and password for the administrator to log into the web user interface are
both “admin” (case-sensitive). Most features are available for configuring via web user
interface. IP phones support both HTTP and HTTPS protocols for accessing the web user
interface. For more information, refer to Web Server Type on page 141.
An administrator can deploy and maintain a mass of IP phones using configuration files.
The configuration files consist of:
 Common CFG file
 MAC-Oriented CFG file
 MAC-local CFG file
Common CFG file
A Common CFG file contains parameters that affect the basic operation of the IP phone,
such as language and volume. It will be effectual for all IP phones of the same model.
