Hello,
Assuming that you are using call manager 5.x and above, you can log into the CLI of the publisher and run sql queries.
Lets say the destination called number is 911, you can sure the query:
run sql select callingpartynumber,originalcalledpartynumber,finalcalledpartynumber,datetimestamporigination from car:tbl_billing_data where originalcalledpartynumber = '911'

I would also suggest you to go through the CDR admin guide for better understanding of CDR data base and functionality.
