I'm told Avaya MM uses Active Directory with the dial-by-name feature through an auto-attendant. We don't want cold-callers to be able to dial our main #, use the dial-by-name feature and have the calls routed to our executives. Our execs do want to use MM with internal calls and calls rec'd to their direct dial numbers. Is there a way to block dial-by-name through the auto attendant for these execs (and still have their names listed in AD for email etc)?
