Presence Services supports multiple Presence/IM domains. By default, users with Avaya Presence/IM communication addresses in different Presence/IM domains can exchange Presence and IMs. You can administer Presence Services to block presence and IM exchange between users with Avaya Presence/IM communication addresses in different Presence/IM domains.

For more information, see Configuring Presence/IM routing domain on System Manager.
