Introduction to the 9640/9640G SIP IP Telephone
Your telephone provides many features, including a Phone screen to view and manage
your calls, a Call Log, a Contacts list, an integrated WML browser, a menu of options and
settings, and access to your voicemail. The 9640/9640G SIP IP Telephone provides this
information in color.
The "G" designation in 9640G means this telephone model has a built-in Gigabit Ethernet
adapter which speeds data transmission. A telephone with the "G" designation is otherwise
identical to its 9640 counterpart in terms of features and functionality.
Not all functions and features described in this user guide may be available on your
telephone. If you find that a function or feature is not available, please contact your system
administrator.
