Call Trace - V9.0

History Log

Product Description

Call Trace enables an end-user to trace their last incoming call whether it was answered or not using an automated trace system rather than a manual trace. The mechanical system traces the originating telephone number calling, even if the call was forwarded via a call forwarding service and is completed after a call, whereas a manual trace has to be set up to trace future calls. Call Trace functions even if another Custom Local Area Signaling Systems (CLASS™) feature has been used, such as Last Call Return.

Call Trace (*57):

  • Both "ends" of the call must be in a CLASS equipped office for feature to work.
  • End-users can issue an order to prevent availability to Call Trace by having their access lines "blocked".

The following access code information is applicable for Plain Old Telephone Service (POTS) and Centrex 21 products, Centrex Plus, Centrex Prime® and Centron® products will receive an access code from your CenturyLink Sales Executive for new accounts and CenturyLink Service Manager for existing accounts. For Centrex 21 follow the instructions below using # instead of * with the access code on a touchtone telephone.

To activate Call Trace with POTS and Centrex 21 products:

  • Press *57 (or 1157 from a rotary telephone) immediately after hanging up from the call to be traced.

The voice response system gives directions for activating the trace and quotes the charge if the trace is successful. If Call Trace is not successful, the end-user receives an announcement advising that the call could not be traced (see manual trap).

After three successful traces, from the same number, call the Annoyance Call Bureau at 1-800-582-0655 to advise that you have activated a Call Trace. If the call is threatening, then CenturyLink does not require 3 successful traces.

Upon your request for assistance you will need to provide the CenturyLink ACB with:

  • Your contact name and telephone number
  • Terminating telephone number
  • A description of the annoyance call(s)

CenturyLink will:

  • Update the description of the calls for each *57 trace
  • Verify the subscriber data
  • Follow procedures for release of *57 trace pursuant to state tariff

Under normal circumstances, deterrent action is taken only after three successful traces to the same number.

Manual Trap

At your request a Manual Trap request will be placed on your end-user's line. You will need to provide the CenturyLink ACB with:

  • Your contact name and telephone number
  • Your end-user's Terminating Telephone number
  • Remote and Host Common Language Location Identification (CLLI) code
  • A description of the harassing or threatening phone call(s)
  • Any other information deemed appropriate
  • A Law Enforcement case number, Officers Name, Phone Number and location

Release of information and deterrent action by CenturyLink:

If the originating call is:

  • A trunk number, CenturyLink will verbally provide a trunk number translation. This may include the CLLI code, Long Distance Carrier (LDX), CLEC and/or independent company information.
  • From a non CenturyLink number, CenturyLink will verbally release the information to a Law Enforcement Agency (LEA)
  • From a CenturyLink number, CenturyLink will release the information to the LEA only.

Misdirected FAX/Computer

From a CenturyLink number that has been identified, through your equipment, for misdirected FAX/computer, CenturyLink will release the information to you. Please submit your request on your letterhead, via FAX. The suspect information will be verified and you will receive a call back or the information will be FAXed.

Emergency 911 Calls

The Law Enforcement Agency (LEA) determines if the situation is an emergency. Examples of a life-threatening emergency include: medical assistance, kidnapping, hostage situation etc.

In an emergency situation CenturyLink will take calls only from the LEA.

If you receive a call from a Law Enforcement Agency or 911 Public Safety Answering Position (PSAP) for technical and/or network assistance you will refer the call to:
