2 clusters::<br>

s2s1-s6<br>

<br>
you could just create 1 ICT on each cluster. Point to the first 3
servers of the remote cluster. Use a device pool that uses a cmgroup
that includes the first 3 servers of the local cluster.<br>
<br>
This will work in all "recent versions" (i'm going to say >=6.x,
roughly) of CUCM where we changed h225d to only run on nodes in the
device pool. <br>
<br>
In older versions (4.x) creating the ICT created h225d on all nodes in
cluster1. this allowed any node in cluster1 to initiate an h225 tcp
session to clsuter2. if cluster2 received an h225 session from c1s4
and that was not configured as an ICT remote destination then cluster2
would reject the session and call would fail.<br>

As far as I remember, it's important to create intercluster trunks in a
full mesh design, so that each subscriber is represented in the ICT of
the other cluster. This is also explained here:<br>
<br>

<br>
Because we have more than three subscribers in our clusters, we'll have
two ICTs on each cluster to ensure the full mesh.<br>
<br>
However, I'm pretty sure you only have to route calls over one of them.<br>
