You can use command line parameters to quick-launch the Communicator 2007 R2 shell. For example, if a user clicks on a phone number in another application, the shell can start an instance of Communicator 2007 R2.

Communicator 2007 R2 can also recognize a semicolon-delimited list of contact names for multi-party conferencing.

If Communicator 2007 R2 is configured to automatically sign in at launch, the shell execution will launch the Contact window. If Communicator 2007 R2 is not configured to automatically sign in at launch, the sign-in window is displayed.
