Understanding Lines vs. Calls

To avoid confusion about lines and calls, refer to these descriptions:

•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. To see your phone lines, look at the right side of your touchscreen. 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.
