Customer Originated Trace (COT), a CLASS feature, enables the recipient of an
obscene, harassing, or threatening call to request that it be automatically
traced, if it was the last call received. The calling party's number and other
call-related information are loaded into the called party's incoming memory slot
and are available for use in tracing a call. Information relating to a call
remains in the incoming memory slot until another incoming call's information
overwrites it.

This document defines the Telcordia view of COT generic requirements for
residential and small business customers. This GR Issue 2 adds Automatic Message
Accounting (AMA) data generation requirements that are consistent with the
Billing AMA Format (BAF) documented in the latest version of GR-1100-CORE.
In addition, Appendix B has been revised to specify how the Incoming Memory Slot
should be updated when an operator-assisted call is received.

This document replaced TR-TSY-000216.

When using GR-216, you may need to refer to GR-1100. You may want to
refer to GR-246 and/or GR-317.
