<p class="MsoNormal" style="margin-bottom:12.0pt">I have infrastructure setup to provide VOIP services as well as other services to a multi-tenacy environment. I want to segregate those services as much as possible for security reasons.<br>
<br>
My question, customer resources are behind a edge router and a firewall, I want my cube positioned as close to the edge as possible for performance reasons. Cisco design docs have suggested that for larger sites terminating SIP traffic on a CUBE that best practice
is to position the CUBE inside of the firewall. My thoughts are a DMZ like structure that connects to the firewall via two interfaces, inside and outside. This provides several controlled interfaces for policy enforcement.
