An illuminated red LED in the upper-right corner of your phone and the Message button on the phone faceplate indicate you have unopened voice mail messages. If Visual Alerting is enabled, the corner LED also flashes when you receive an incoming call. Depending on your system configuration, the message waiting indicators indicate messages either for the phone extension, or for the Agent Login ID after agent login. When configured for Agent Login ID, the message waiting indications are for the agent when the agent is logged in. Immediately after agent login, the phone screen displays MWI is indicated for the Agent ID or MWI is indicated for the extension.
