<BR>
The answer to this depends on what you mean by “talk to each other”.<BR>
<BR>
We can build Inter-cluster Trunks (ICTs) between different versioned CCM clusters but this simply allows the passing of calls to and from the different clusters. What else are you looking to do between clusters of different versions?<BR>
