Understanding Lines and Calls
The terms lines and calls can be easily confused.
Lines—Each corresponds to a directory number or intercom number that others can use to call
you. Your phone can support up to eight lines, depending on your phone and configuration. To
see your phone lines, look at the right side 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.
