Chapter 29: Understanding Wave Call Routing
Wave Global Administrator Guide
In the single call outside line variant a single trunk is associated with an Outside Line feature
button on a digital phone. The LED next to the Outside Line button indicates when the trunk is
in use by any phone. For outbound calls, when a user presses the Outside Line button, the LED
is lit red where it appears on other phones, and cannot be used on any other phone. Once the call
is connected the LED indicates whether break-in is allowed. For inbound calls, the Outside Line
button LED flashes yellow, and the phone can be configured to ring. Once the call is answered
the LED indicates whether break-in is allowed.
Multiple call variant
The following diagram illustrates a multiple call outside line variant:
In the multiple call outside line variant an Outside Line feature button on a digital phone is
associated with more than one trunk line. If any trunk line is available for outbound calls, the
Outside Line button LED will not be lit on any phones with the button. The LED next to the
Outside Line button is red when all of the associated trunk lines are in use. For inbound calls,
the Outside Line button LED flashes yellow, and the phone can be configured to ring. When the
call is connected, if there are any available trunk lines the Outside Line button LED will not be
lit. If no trunks are available the LED is red. Break-in is not supported in the multiple call
variant.
