I found out CUIC Agent Detail Report shows multiple calls with 0 Talk Time and their Call Duration equals to Select Resource Timeout Value. I am not sure these calls are proper calls from callers or abandoned call, since information of these calls do not match the abandoned time stated in the Abandoned Call Detail Activity report.
I have found multiple documents suggesting this timeout value should be less than line Forward No Answer Timer. I wounder if it is the cause of these strange calls.
