There isn't a report in the PBX for that and I don't thing Prairie Fyre can do that either.

Looking through the SMDR logs, i was able to determine that an entry with a C before the extension is a silent monitor connection.  
As seen here: 
09/10 09:56:18  0000:01:07 6538    0006 6533                      I 6533           
C 6515                  007               
This example shows 6515 was montoring 6533.
My next question.....
Need to get the Logsys read results to a file, but the buffer window is too small.  So I found the command 
LOGSYS READ SMDR INTO.  I am trying to do a LOGSYS READ SMDR INTO (filename) ALL MATCH 6533....but i am not sure how to specify the file and how to retreive it.  Any idea?
I am on a local computer in office going to the web address for the ICP3300.  Is there a better way I should be doing this?
Thank
