Simple Call - Meridian 1 Proprietary Sets

Set A, the calling party, initiates a call to Set B, the called party. Set B has
Class of Service Malicious Call Trace Allowed (MCTA) configured. With
Called Party Control on Internal Calls (CPCI) activated, Set B can activate
Malicious Call Trace even after Set A has gone on-hook. This operation
is possible because Set A is not idled until Set B has gone on-hook.
Depending on the type of telephone, CPCI activation is done by completing
the following:
Step Action
1Enter the SPRE code and "83" access code;
2Dial the Malicious Call Trace (MCT) Flexible Feature Code (FFC) or
3Activate the Call Trace key.
—End—
With Called Party Control on Internal Calls, Set B can activate the Malicious
Call Trace feature during an active call between Set A and Set B as well as
after Set A has gone on-hook. Set A is not idled until Set B goes on-hook.
