Without a firewall
In the example below, there are three geographically separate offices: Head, Branch and Home. All

There are no firewalls involved in this scenario, so direct links can be configured between each of the

In this scenario, a call placed between the Home Office and Branch Office will consume bandwidth
from the Home and Branch subzones and on the Home and Branch pipes (Pipe B and Pipe C). The
Head Office’s bandwidth budget will be unaffected by the call.
