Notes: 1. Timestamps (hh:mm:ss format) are required. Milliseconds (hh:mm:ss.sss format) are highly recommended 2. Make sure the syslog prefix is removed (to exclude confusion with IOS debugs) 3. Q.931 messages for calls established before the logging started are ignored 4. Sorting works correctly if the number of calls is less than 1'000'000 and the number of records (lines) per call is less than 100.
