You have to use intercluster non-gatekeeper controlled . I do nothink there is special document for this , but you can see the below link:-

Other than the ICT to connect

Other than the ICT to connect the two clusters, it all comes down to call routing, route pattern, partitions and CSS, nothing else. Route the call from 7 to 9 via ICT, and make sure you can reach the FXO on 9.
