When OpenStage is configured as a keyset device with multiple lines, then uaCSTA services can only be 
applied to the primary line of the OpenStage device, and secondary lines cannot be controlled using 
the uaCSTA interface. 
 
When invoking call related services (e.g. AnswerCall) and physical devices services (e.g. SetMicropho-
neMute), it is the OpenStage device which decides which call or speaker the service request is applied 
to.
