Understanding Lines vs. Calls
To avoid confusion about lines and calls, refer to these descriptions:
• Lines—Each corresponds to a directory number that others can use to call you. The
Cisco Unified IP Phone 7960G supports up to six lines and the Cisco Unified IP Phone 7940G
supports up to two lines. To see how many lines you have, look at the line area of your phone
screen. You have as many lines as you have directory numbers and phone line icons.
• Calls —Each line can support multiple calls. By default, your phone supports four connected calls
per line, but your system administrator can adjust this number according to your needs. Only one
call can be active at any time; other calls are automatically placed on hold.
Understanding Line and Call Icons
Your phone displays icons to help you determine the line and call state.
