Call Trace - Log File Overview

Call Tracing gives the IMG 2020 the ability to view various pieces of information on a per call basis. The Web GUI will allow up to 4320 minutes (72 hours) of Call Tracing. Call tracing uses NFS to write the files to an NFS Server. The call trace is logged into a file for viewing at a later date. A call trace log includes the following information:

The Call Trace is saved to a log file in the directory configured in the NFS Mount Directory field of the Call Tracing object. This directory is located in the NFS Server configured in the NFS Server field of the Call Tracing object.
