pbxnsip – Log Filename
To request that the system write log messages to a filename, specify that filename here. If you put a dollar sign into the log filename, the system will replace the dollar sign with the current day and automatically generate a new file everyday. This will ensure that the log files do not become too large over time. This is highly recommended;otherwise, do not log to a file at all. Also, be sure to delete old log files fromtime to time so that your file system does not get overloaded with too much logging information.
