Securing Your Grandstream PBX - UCM & GCC Series

Securing Your Grandstream PBX - UCM & GCC Series

In this video I am going to show you how to further enhance the security of your Grandstream IP PBX (applies to GCC and UCM series) by enabling, disabling or changing various settings in the PBX Web Interface. So if you have or are thinking of having an IP PBX for your home, business, school or commerce then you may well find this video useful.

As I mentioned in the video I am using a Grandstream UCM6300A model of IP PBX which is already behind a firewall and the UCM and all connected Grandstream IP SIP phones are sitting in their own VLAN which has Firewall Rules applied so that other VLANS cannot access the PBX VLAN.
