Understanding Feature Functionality and Availability
The operation of your Cisco IP Phone and the features available to you may vary, depending on the
call processing agent used by your company and also on how your company's phone support team has
configured your phone system. Therefore, some of the features included in this Phone Guide might not
be available to you or might work differently on your phone system. Contact your support desk or
system administrator if you have questions about feature operation or availability.
Call-Handling and Navigation Tips
These guidelines can help you handle calls and navigate menus on your Cisco IP Phone.
Going On-Hook and Off-Hook
Some phone tasks and instructions differ depending on whether the phone is on-hook or off-hook.
• On-Hook—The phone handset is resting in the cradle, no calls are active, and you do not have an
active dial tone. Your phone provides on-hook dialing, which enables you to enter or choose
phone numbers before activating the call. When your phone is on-hook, this icon appears next to
each phone line:
• Off-Hook—The phone handset is lifted from the cradle, the speakerphone is active, or any of
several other methods are used to get a dial tone or to answer an incoming call. When your phone
is off-hook, this icon appears next to the appropriate phone line:
Understanding Lines vs. Calls
It is sometimes easy to confuse lines and calls on your phone. Use these tips to avoid confusion:
Lines
The Cisco IP Phone 7960G supports up to six lines and the Cisco IP Phone 7940G supports up to two
lines. The number of lines available on your phone depends on how your system administrator has
configured your phone's programmable buttons. To see how many lines you have, look at the line area
of your phone screen. You have as many lines as you have phone numbers.
Calls
Each line can support multiple calls. Therefore, you might find yourself handling several calls on one
phone line. The default configuration is four calls per line, but your system administrator can adjust
this number according to your needs. Regardless of the number of lines, your phone supports a
maximum of 200 calls at a time.
