CALL PROCESSING TRACE (CPT)
The Call Processing Trace (CPT) logs all call processing and messaging activities and events to one file
on the hard disk drive. The CPT logs events for the following activities:
-
Mailboxes
-
Ports
-
Network locations (Analog and Digital networking activities are logged separately.)
-
Message headers
-
Integrations
-
Applications processors (Works for Serenade)
-
Client-Server Protocol (Used to trace activity for OctelDesigner Applications)
The CPT logs activity detected by the Octel Overture 200/300. The CPT can be used to determine, for
example, why a caller entering 399 received the response “Extension 39 is invalid.” The CPT can help
determine the port that was used for the call. However, the reason for the failure requires extensive testing
to determine why a digit was not detected. Possible reasons might include the caller’s instrument,
transmission quality, or any other interruption in the transmission path during sending of the DTMF digits.
The CPT is a diagnostic aid that is designed to be used when a detailed customer complaint is received.
When used correctly, the CPT helps to verify or explain problems, such as late delivery or reappearing
messages.
When the CPT function is used as part of the process to determine why something unexpected happened,
several points should be considered:
-
The PBX numbering plan
-
The Octel Overture 200/300 mailbox/extension numbering scheme
-
The extension numbers assigned to the Octel Overture 200/300 ports
-
The PBX function and feature-access codes
Using the CPT Log
When an unexpected event is identified in the CPT, the first step is to backtrack and attempt to
understand all activity reported before the event. The CPT stores several hours of activity for a large,
high-traffic message server and up to several days of activities for a small, low-traffic message server.
To collect and analyze specific call processing and message activities, you can use either the
LIST
TRACE
command or the
LOG PR CPT
command.
These commands provide two different methods of printing log records.
