34Compact Plus System Administration Guide P0607114 Issue 01Prime line for an extensionA line can be assigned to a telephone as its primary line to usewhen making an outgoing call. This feature saves the user timebecause the system automatically selects the line rather than theuser having to select the line.See "Assigning a Prime line to an extension" on page 42.Redirect ringWhen this feature is turned on, the telephone gives an audiblesignal whenever a call has been redirected. This reminds you thata line has been redirected using the Line redirection feature andserves as a cue to turn the feature off.For example, you have re-directed line 1 to another extension inthe network. If Redirect ring is on, you hear a short ring everytime a call on line 1 is forwarded to the other telephone.See "Activating Redirect ring" on page 109.Trunk answerThis feature is active by default for all Service modes. This meansthat during non-business or non-busy times, any extension cananswer calls ringing at any other extension. It does not matterwhich lines appear on the extensions. It only matters that the lineitself has been placed in a Service mode using its Controlextension.For example, during the lunch break between 11:30 a.m. and 1:00p.m., lines 1, 2, and 3 are put in Lunch mode. Trunk answer isactive, so whenever any extension rings, Mr. Cassidy, who acts asa temporary attendant, can answer from his extension.See "Using alternate or scheduled services" on page 158.Answer extensionIf your telephone has an Answer key for another extension, youcan answer calls that come in for that extension on yourtelephone.For example, Mr. Cassidy’s telephone has an Answer key forMiss Vale. When Miss Vale’s telephone rings, Mr. Cassidy cananswer it on his telephone by pressing the Answer key. MissVale’s extension has been assigned as an Answer extension onMr. Cassidy’s telephone.Simply press the Answer key when you hear the other person’stelephone ringing.See "Answer keys" on page 242.
