Prolog information

Metadata

Keywords:

This menu displays extensions that have attempted to register using the wrong password.

Extensions are blocked after five failed registration attempts within a 10 minute period.
The extensions are blocked for 10 minutes.
Whilst blocked, further registration attempts are ignored even if correct password details are entered.
For non-Avaya phones, if the extension continues to attempt to register during this period its blocking time is extended.
When an extension becomes blocked, the system also generates an alarm in System Status Application application and adds an entry to the audit log. A system alarm is also generated and can be output using any of the configurable system alarm routes.
The IP address of a phone attempting to register can also blocked, see, Blacklisted IP addresses. A phone can also be blocked from registering if it becomes quarantined, see Quarantined Phone Status.
