<div dir="ltr"><div><div>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. <br><br></div>I
wanted thoughts from the community on real world network design best
practices when aggregating multiple tenancy environments providing VOIP
with CUBE services.<br><br><br></div><div>thanks in advance,<br></div><div><br></div>Mike </div>
