<p class="MsoNormal">Hi Mike,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">You need zones and search rules, it doesn’t inherently know what to do with it.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">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.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So <o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<ul style="margin-top:0in" type="disc">
<li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo2">Traversal zone (c and e)<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo2">Search rule to match something on the E -> C over that zone<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo2">Neighbor zone (c)<o:p></o:p></li><li class="MsoListParagraph" style="margin-left:0in;mso-list:l1 level1 lfo2">Search rule to match the cluster fqdn C -> UCM over that zone<o:p></o:p></li></ul>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Then that needs to have a trunk that will accept the call with the right CSS.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I did not reuse ports and have a different trunk for it. I think this is in the guide but the guides are confusing.<o:p></o:p></p>
