Domains
On the Domains page, you can add administrative domains to or remove them from the list of domains from
which registrations are accepted.
If the list is empty, all domains are considered local, and the system accepts endpoint registrations from any
domain. Otherwise, it accepts registrations only from the listed domains. This is a supercluster-wide
configuration.
Dynamically blacklist signaling
from hyperactive endpoints
If this option is selected, the Call Server adds H.323 endpoints to its blacklist
(ignoring their signaling messages) when they send duplicate RRQ or GRQ
messages in excess of the criteria you specify below.
When an endpoint is blacklisted, the Call Server:
• Stops interpreting, responding to, auditing, or logging messages of that
type from the endpoint.
• Creates Alert 5002 and corresponding SNMP trap.
• Logs the blacklisting.
Gatekeeper Blacklist Settings
Message Type You can specify the blacklist settings separately for RRQ (Registration
Request) and GRQ (Gatekeeper Request) messages.
Threshold The number of duplicate messages within the specified interval that causes
an endpoint to be blacklisted.
Interval (msec) The interval in milliseconds to which the threshold applies.
Quarantine If this option is selected, endpoints that are blacklisted are also quarantined.
They remain in Quarantined or Quarantined (Inactive) status (unable to make
or receive calls) until manually removed from quarantine. See Endpoints on
page 91.
Apply to VBP If this option is selected, video border proxies (VBPs) can be blacklisted. If a
VBP is blacklisted, none of the endpoints behind it can register.
Remove non-hyperactive
endpoints from blacklist
after specified interval
(minutes)
The interval for which an endpoint must be well-behaved (that is, not exceed
the blacklisting threshold for the specified interval) in order to be removed
from the blacklist and once again allowed to register.
When an endpoint is removed from the blacklist, the Call Server:
• Starts interpreting, responding to, auditing, and logging messages of that
type from the endpoint.
• Clears the alert and SNMP trap.
• Logs the removal from the blacklist.
Note: If the endpoint was quarantined as well as blacklisted, it remains
quarantined.
