Branch Office
If you are in a branch office, following two options are suggested:
Option1:
Deploy the VC120 following the same steps as for the head office. In this way, both inbound
and outbound calls are available.
Option2:
Deploy the VC120 using an intelligent firewall, which means that plug and play is possible
without any further firewall configuration, but only outbound calls are available.
Please note that when the VC120 is deployed with an intelligent firewall, you have to open ports (as shown
below) permission if they are restricted

It is recommended that you forward the web management port(443/TCP) to the public network, so that the
head office can remotely manage the branch office.
