Line keys
Line keys programmed to an extension
control inbound and outbound calls.
Line keys programmed to an extension
indicate the status of the call being controlled
by the key.
• Blinking green = incoming call or call on
hold
• Solid green = active
Line keys not programmed to an extension
may be programmed as speed dials, etc.

helpful things you can do when using your

appear as a soft key.
