Cross server chat rooms

My environment now has two jabber servers, each with separate domains. Ive gotten S2S to work such that users can IM each other, which is great. Is it possible to have users join chat rooms that reside on the server that they arent logging in to, which is also another domain?

I should add im not 100% on jabber terminology, so this may exist already and i just didnt search for the correct term. If so, a simple push in the right direction would be appreciated.

figured it out - had to add CNAME records for conference and search, and then whitelist those in the S2S connection settings and restart it per http://community.igniterealtime.org/message/191256#191256
