Feature Description
Lets you make or receive a single call. There must be an available and
idle call key to make or receive a new call.
The VLKW shows the current call state.
A call key may be bound to a service that is a Shared Line. In that case,
when no call is on that key, the VLKW information reflects the state of
the respective Shared Call Appearance (SCA).

events include Ringing, Holding, In Use, and Idle.
The VLKW shows the monitored service name and account user name
(usually same as the account DID number or extension).
This function must be bound to the specific voice service that it monitors.
