<p class="MsoNormal"><span lang="EN-AU">Good day all,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">I had setup an Expressway for video traversal. B2B video was fine. But then in preparation for Collab Edge had the customer insert some SRV records and it screwed inbound video calls. Does anyone know the best practice
for implementing these records?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">The setup is:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">Expressway E version 8.1<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">Expressway C version 8.1<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">CUCM version 9.1(2)SU1<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">Customer has a DNS alias of video.customer.com.au pointing to their Expressway.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">Inbound and outbound video calls are fine. I have can make inbound calls to the MCU by using
<a href="mailto:meeting@video.customer.com.au">meeting@video.customer.com.au</a><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">Then we configured the following DNS SRV records:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">_<i>collab-edge.</i>_tcp.customer.com.au

<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">Something in the SRV records for SIP caused inbound calls to stop working.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-AU">Inbound calls to <a href="mailto:meeting@video.customer.com.au">
meeting@video.customer.com.au</a> fail. However inbound calls to <a href="mailto:meeting@%3cip.address">
meeting@<ip.address</a>> continue to work.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">The VCS Expressway was showing no inbound calls in “call history” or “search history”.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">Is there another way to check to see if the call is even hitting the Expressway?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">The VCS E&C have both the domain of customer.com.au and video.customer.com.au. The endpoints, MCU, etc are registered to the VCS as
<a href="mailto:endpoint@video.customer.com.au">endpoint@video.customer.com.au</a><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">Is the Expressway getting confused with the two domains? Would anyone have a good working example of how Collaboration Edge should be deployed?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-AU">I have been referring to this guide: <a href="http://www.cisco.com/en/US/docs/voice_ip_comm/expressway/admin_guide/Cisco-Expressway-Administrator-Guide-X8-1.pdf">
