Administration, Policies, and Routing
Administration Plan
The videoconferencing administration plan allows the system
administrator to manage user permissions and network policies.
Your plan should define:
❑
Superusers
❑
Administrators
❑
Permissions for groups and for individuals
❑
Policies such as bandwidth allocation per user
Default Group Policy
A group policy allows you to define dialing properties, services, and
bandwidth management parameters for all members of a defined
group without having to configure these individually for each user.
The default group is normally all users, and the policy settings for
this group are the default group policy. The administrator sets
policy, services, and other settings for this and other groups.
Least-Cost Routing
Least-cost routing enables calls that originate inside the
organization to be routed in the manner that incurs the lowest
expense. In order for least-cost routing to be implemented, the
network topology must be defined — the gateways on each
network, WAN link capacities, and other factors.
Each gateway has an associated least-cost routing table which is
created by the administrator. The table consists of dial string entries
(country code, area/city code, etc.) and cost. For calls between
networks, the tables are compared to identify the least-cost route for
the call. Least-cost routing will not be used if the least-cost route
cannot be identified, if the required resources are unavailable, or if
bandwidth limitations exist on the WAN link.
