Aastra Telecom 4223 manual Secret of Identity, Tracing Malicious Calls

More Features of Your Extension

Secret of Identity

When your facility is connected to the ISDN network, your identity is usually transmitted to your external calling parties, and vice versa.

According to the specific right assigned to your extension, it is possible that your identity not be divulged to your external ISDN network calling parties.

This is therefore systematically valid for all of your outgoing ISDN network calls, without any specific action on your part.

Your identity is divulged, however, for your internal calls, and you still receive the information concerning your external incoming calling parties.

Tracing Malicious Calls

It is possible that at some time, you may be subjected to malicious calls from external parties (usually received from an ISDN network) who hide their identity. See the “Operations for Incoming Calls” section.

When your facility is connected to the ISDN network, you may request that these malicious calls be traced, thus finding out the malicious caller’s name and number, and that this information be saved on the public network.

This assumes, however that you have made a prior request to the operator responsible for the public network to which your facility is connected.

Assuming this condition has been met, requesting a malicious call tracing may be carried out on an established call, whether in single or enquiry mode, as well as when the call is being disconnected by the remote malicious caller.

To do this, during a call:

2 times >> Press the Next key twice in order to display the following screen:

FRI 20-APR 15:28
L1 Aastra-00164477500	01:33
RECORD	MALICIOUS <

MALICIOUS Press the dynamic function key shown on the left.

Your request for malicious call tracing is transmitted over the ISDN network, and the call proceeds normally.

If the call is being disconnected by the remote caller, all you need to do is disconnect the call yourself.
