SoundPoint IP Phone Terminology
Before you read this document, it is important to understand the following
phone-related terminology:
• Attendant phone—The phone you use to monitor a remote line. The
phone has optional Expansion Modules and is set up to monitor one or
more remote lines using the BLF feature.
• Remote line—The remote line the attendant phone monitors.
• Idle state—The phone is “on hook” and there are no active, held, or
incoming calls.
• Active state—There is an active call in progress.
• Alerting state—There is an incoming call (the phone is ringing, if
configured with a ring tone).
• Call waiting state—There is an active call in progress and the phone is
ringing. (There may be held calls also.)
• Directed call pickup—You can answer an incoming call on a remote line.
