This feature is available for IBM Notes 8.0.1 and above.
harmon.ie makes it easy to communicate with people, by e-mail, chat, phone calls, and video calls:
The business cards shown in the People tab and the people information pane include icons to Send an instant message (), Call (), or Send an e-mail message (). Click an icon to start communicating with this person. Learn more about finding people and about the business card.
Wherever a user name is displayed in harmon.ie (for example in the Sites tab in columns that refer to users, in the Note Board or the Version History panes) it is displayed with presence awareness (Active, Away, Do Not Disturb, and so on). Right-clicking the presence awareness icon brings up an instant messaging context menu, which lets you start communicating with this person, by chat, voice or video call, and e-mail.
