Customer Originated Trace

Description
Customer Originated Trace is one of the Local Area Signaling Services (LASS)
features. With the Customer Originated Trace feature, the user can call the
central office to obtain the telephone number from which the incoming call was
received on the BRI line without placing a call to the telephone number.
Customer Originated Trace can be activated on any multiline telephone with a
Personal Line button for the BRI line on which the call was received. The
telephone from which Customer Originated Trace is activated does not have to
be the telephone used to answer the call.
The user should select the Personal Line button representing the BRI line as
soon as possible after receiving the call. If another call is received on the BRI
line assigned to the Personal Line button, the original call can no longer be
traced.
NOTE:
The requirements on the release of the telephone number vary depending on
locality. In some cases, you are required to obtain the information through the
local law enforcement agency. Contact the local telephone company for
information on local requirements and on feature use.
Considerations and Constraints
Trace information cannot be requested for a call in progress on a BRI line. The
user must hang up before activating the Customer Originated Trace feature.
Customer Originated Trace should be used for calls received on Personal Line
buttons only.
Mode Differences
In the Hybrid/PBX mode, Customer Originated Trace should not be activated for
calls received on any type of System Access button or on a Pool button because
there is no way to identify the last BRI line used to receive a particular call.
