Yes, telcos do this, but they (used) to have the same problem we all have in the ISP world, in that your average DMS-100 voice switch is optimized for call processing, not for call-detail searches. Your average call-detail search used to take 1-2 hours for a 5 minute window. (I say "used to" as now the SS7 STP processors now do the call-detail recording, and call lookups are a matter of keystrokes and seconds away.) Router mfgrs are still in the stages of switching packets as fast as they can, not detail management. And of course, nooone of us want to drop our routers down to process switching to track packets.
Or if your answer is that telcos only do it for the police and not for each other, then my question would be why can't we form an Internet equivalent, maybe affiliated with something like CERT, that can make these requests and with whom NSP's would cooperate.
Telco call-detail lookups for law enforcement constitute <-.01% of those lookups (I did work at MCI's Western Region Net Mgt canter). All the other lookups are for maint purposes (like finding marginal trunks, tracking call patterns, making sure routing databases are working right, etc). It's obviously going to be different in our case. rob. - - - - - - - - - - - - - - - - -
