Device Adapter publishes the Presence status of the endpoints that are migrated to the Avaya Aura® solution. The Presence status indicates whether a migrated endpoint is active or inactive, that is, on a call or not. These migrated endpoints are not presence capable. The Presence status of the migrated endpoints is published so that other Presence-capable endpoints that are within the Avaya Aura® solution can display it to the interested users.
