Cisco 7940 Phone Guide - Page 20

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. Icon Call State Description On-hook line No call activity on this line. Off-hook line You are dialing a number or an outgoing call is ringing. Connected call You are connected to the other party.
