System Manager supports the ability to assign a tenant ID to a user. For more information about tenant management, see Administering Avaya Aura® System Manager guide.
On enabling Multi-tenancy, Presence Services:
Blocks presence and IM sharing between users assigned to different tenants.
Does not notify a user of any presence state changes if the contact is assigned to a different tenant.
Does not deliver IMs if the sender is assigned to a different tenant than the recipient. Presence Services sends an XMPP message to the sender indicating that the IM has been blocked.
