We currently share our CUCM and Unity Connection Cluster with another company. They are interested in adding Jabber to their environment. They run completely separate and inter-domain communication is not required, however, their domain is separate.
Is it possible to have two domains sharing a single Presence server?
Not with 9.x, you'd need to upgrade to 10.x+ in order to use multi-domain, and you won't have any kind of separation between them, if they know the JID of users in the other domain, they can add them.
