Emergency Notification
When any extension dials an emergency number, the system can make calls to specified
extensions, groups, or outside numbers. To configure this option, select the extension/
group/outside number, and check the
When Emergency Number Has Been Dialed
check box.
Emergency-number calls are logged to SecurityAlert.txt (see “Where Security Alerts Are
Logged” on page 201.)
Unusual VM Activity Notification
When certain unusual activity is detected from an extension’s voice mail, the system can
notify a designated extension. This option is intended to help detect if a hacker has
obtained control of and is making calls from an extension’s voice mail. To alert an
extension (usually the administrator) when either of the following abnormal activities are
happening, select the extension and check the option
When unusual call activity has
been detected :
• When calls made from voice mail are unusually long (by default, more than 120
minutes)
•
When the number of calls made from voice mail is unusually high (by default, more
than 20 calls in one voice mail session)
When the designated extension is notified, the system will play "Unusual call activity has
been detected from Extension xxx. More than yy calls have been made from the
extension's voice mail. Please verify with the extension user." Or "Unusual call activity
has been detected from Extension xxx. The extension made more than a yyy-minute call
from the extension's voice mail. Please verify with the extension user." The security
notification will be made only once within a call.
