Cisco Systems 7931G manual Understanding Lines and Calls

Understanding Lines and Calls

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

•Lines—There are 24 programmable buttons (see Understanding Buttons and Hardware, page 9). Typically, your system administrator assigns some of these lines (up to 24) to be used as lines for making and receiving calls. Each corresponds to a directory number or intercom number that others can use to call you.

Some of your lines may share the same directory number, and others may have unique directory numbers. To see your phone lines, use the Navigation button to scroll through the list of programmable button display (see Understanding Phone Screen Features, page 15).

Buttons configured as lines display their assigned directory number and associated button number. For example, if you have directory number “3105” assigned to button 1, the line appears as 3105:01 on the phone screen. Each line also has an associated icon to help you identify its purpose (see Understanding Line and Call Icons, page 14).

•Calls—Each line can support a single call. If multiple lines share a directory number, each line can still support one call each.
