Thanks for your reply. I think its a problem with Webex Control hub. I went through a bunch of old Cisco live Hybrid presentations and looked a the debugs from the trouble shooting section. It looks like Control Hub is adding "cluster1" to the invite. Look
at the screen shot below.</div>

Hi Mike,</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
You need zones and search rules, it doesn’t inherently know what to do with it.</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
In our system, we have a search rule set for any alias in from the E cluster across a traversal zone towards the C cluster. I sieve out the garbage with call policy language on the E cluster.</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
On the C itself, I have a neighbor zone back to the UCM cluster with a search rule for the cluster fqdn which is what these requests are going to come in as. That zone is then explicitly configured for the call processing nodes in the cluster.
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
The E’s default behavior (maybe the C too I don’t route through it otherwise) is to go off and do a search for SRV records for the domain if you let it attempt to search and forward off the internet so that’s probably why you’re seeing that.</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
So </p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<ul style="margin-bottom: 0in;margin-top:0in" type="disc">
<li class="x_MsoListParagraph" style="margin: 0in 0in 0.0001pt 0.5in; font-size: 11pt; font-family: "Calibri", sans-serif;margin-left:0in">
Traversal zone (c and e)</li><li class="x_MsoListParagraph" style="margin: 0in 0in 0.0001pt 0.5in; font-size: 11pt; font-family: "Calibri", sans-serif;margin-left:0in">
Search rule to match something on the E -> C over that zone</li><li class="x_MsoListParagraph" style="margin: 0in 0in 0.0001pt 0.5in; font-size: 11pt; font-family: "Calibri", sans-serif;margin-left:0in">
Neighbor zone (c)</li><li class="x_MsoListParagraph" style="margin: 0in 0in 0.0001pt 0.5in; font-size: 11pt; font-family: "Calibri", sans-serif;margin-left:0in">
Search rule to match the cluster fqdn C -> UCM over that zone</li></ul>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
Then that needs to have a trunk that will accept the call with the right CSS. </p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
</p>
<p class="x_MsoNormal" style="margin: 0in 0in 0.0001pt; font-size: 11pt; font-family: "Calibri", sans-serif;">
I did not reuse ports and have a different trunk for it. I think this is in the guide but the guides are confusing.</p>
