Call Trace - V8.0
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 (CLASSTM) 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 Qwest Sales Executive for new accounts and
Qwest 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 Qwest does not require 3 successful traces.
Upon your request for assistance you will need to provide the Qwest ACB with:
- Your contact name and telephone number
- Terminating telephone number
- A description of the annoyance call(s)
Qwest 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 Qwest 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

- From a non Qwest number, Qwest will verbally release the information to a Law Enforcement Agency (LEA)
- From a Qwest number, Qwest will release the information to the LEA only.

The suspect information will be verified and you will receive a call back or the information will be FAXed.
