Counter Description
This counter indicates the total Cisco IME voice call records (VCRs) that are
stored on the Cisco IME server after receiving calls. You can use these records
for validating learned routes.
This counter indicates the total number of attempts that the Cisco IME server has
made at performing a validation because the dialed number was found in the
Cisco IME network. This counter provides an overall indication of system
usage.
This counter indicates the total number of destination phone numbers that have
been validated, but that are awaiting further calls to improve the security of the
system. If you use a higher level of security for learning new routes, the Cisco
IME server requires multiple successful validations for a route before that route
is available for calls over IP. This counter tracks the number of successful
validations that have not resulted in available IP routes.
This counter, which is an integer, indicates the number of scheduled validation
attempts to retrieve a learned route. This value indicates the backlog of work for
the Cisco IME service on the Cisco IME server.
An alert gets generated when the value rises either above the high watermark or
falls below the low watermark. After the high watermark is reached, an alert gets
sent immediately and then once an hour until the value falls below the high
watermark. When the high watermark is reached, the Cisco IME service cannot
clear the backlog of work prior to the expiration of data; this situation causes
records to drop, and validation may not occur. To reduce the workload, add more
Cisco IME servers that can share the workload.
This counter indicates the number of times that the Cisco IME service rejected
a validation attempt because the calling party was not trusted; that is, the party
was on a blacklist or not on a whitelist. This value provides an indication of the
number of cases where a VoIP calls cannot happen in the future because of the
blocked validation.
