voip_users and voip_admins
voip_users and voip_admins are default networks added when the SMC is
initially configured. These default networks are placeholder networks used in
rule creation. The networks are fully customizable and have no relevance
other than as placeholders.
voip_users
The voip_users network refers to user-level access; that is, access by IP
phones and other devices that use the multimedia services of the CS 1000 or
MCS installations. By default, this network maps to all IP addresses. You can
either constrain this definition to suit the internal network or redefine it as
needed.
voip_admins
The voip_admins network refers to management-level access by subnets/IP
addresses that can launch management applications on the VoIP/Multimedia
equipment. By default, the voip_admins network defines no subnets and
provides no access to these interfaces. You must update this network with
specific management IP addresses or subnets before any auto-generated rules
containing the network will be accessible.
