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