Multi Address Appearance on OpenStage 00.00.2007 I 22
Limitations
When OpenStage is configured as a keyset device with multiple lines then uaCSTA services can only be
applied to the prime line of the OpenStage device, secondary lines cannot be controlled using the
uaCSTA interface.
When invoking call related services (E.g. AnswerCall) and physical devices services (E.g.
SetMicrophoneMute) it is the OpenStage device which decides which call or speaker the service
request is applied to.
