is the third article in the series where I explain how Communicator
works with OCS and various other components. This article is about
Remote Call Control, which is a feature that we shipped with Office
Communicator 2005 as well. Remote Call Control allows Office
Communicator to control a PBX phone, through a SIP/CSTA Gateway. The
article touches upon configuration and how Communicator connects to the
SIP/CSTA Gateway. It then covers an end to and call flow of how a basic
call is made and how a basic call is answered.
