There is a major difference between ISP surveillance capability and ISP record-keeping. What is described in the thread is not merely ensuring the ability to monitor user activity persuant court orders but rather maintaining a permanent, comprehensive record of user activity. Those are hardly the same.. As best I can tell, CALEA does the former, not the latter.
This is correct. Surveillance, not record-keeping, is the intent and purpose of CALEA.
BTW, there is a companion requirement with the surveillance requirements... A "confidentiality gaurantee".
Basically, covered communication types must be gauranteed "secure" ( you can't be hacked ) while at the same time, building in a standard means of "tapping".
