You can see the online status of a buddy in the Buddies screen if the buddy is a user on your Teo UC System.
Notes – the Teo UC phone number must be entered in each buddy's IM URI field. Make sure that
Enable IM & Presence is set to ON in Preferences.
The presence status for all buddies in the list will be shown. The icon changes immediately when a person's status changes.
