Malicious Call Tracing

If you are being disturbed by bothersome or malicious external incoming
calls, it is possible to request number tracing from the network provider.
Tracing can be invoked during or after a call.
When malicious call tracing (MCT) is enabled, a signal is sent to the
switched telephone network (PSTN) before the malicious call is discon-
nected. If the calling subscriber clears the call, the external line can be
held for a limited period of time to invoke MCT.
The MCT feature registers information about the origin of the call, that is,
the number of the calling party, and date and time of the call.
Note: The MCT feature can be assign to a shortcut key by the system
administrator.
Ordering Malicious Call Tracing
To order MCT during a call, press the MCT shortcut key.
Note: If no shortcut has been programmed, press Hold and dial *39#.
• If the request is accepted, the shortcut key indicator is lit, a text
message is displayed, and an acceptance tone is heard.
• If the request is rejected, the shortcut key indicator flashes rapidly,
a text message is displayed, and a reject tone is heard.

Monitoring Keys

A monitoring key (or MNS key) is a key that allows you to monitor and
answer calls to other extensions, as well as make calls to the monitored
extension.
Note: MNS keys are programmed as a shortcut keys by the system
administrator.
The monitoring feature is especially useful in Boss-Secretary applica-
tions.
You answer a call to an monitored extension by pressing the shortcut
key which the extension has been programmed to.
