Description
Assigning static addresses to core VVoIP devices permits tighter control using ACLs on firewalls and routers to help in the protection of these devices. NOTE: In the event DHCP is used for address assignment, ensure the DHCP server assigns the same address to the core VVoIP device each time one is requested.
