[comp.dcom.telecom] Telephone Call Data

dfim%tank.uchicago.edu@oddjob.uchicago.edu (Don ) (12/20/88)

I really need to know how/if long-term backups are made of telephone call
data.  My problem is this:  I have an origination number, a destination
number and an approximate time (January 1 - 9, 1979), but one party
insists that the calls were never made.  The local phone company
tells me that records are only kept for six (6) months then
destroyed.  I just can't believe this has always been the procedure.
Years ago microfilm was used, I know that much.

If there is anyone out there with any information (either relating
specifically to the Winnetka area, Illinois, or generally) please
reply with information or names of those with information.

Thanks
Don McLellan
