Understanding Lines vs. Calls
To avoid confusion about lines and calls, refer to these descriptions:
• Lines—Each line corresponds to a phone number (or extension) that others can use to call you.
Your phone can support one line.
• Calls—Each line can support multiple calls. By default, your phone supports up to six connected
calls, 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 call and line state (on-hook, on hold, ringing,
connected, and so on).
