Hehe.... nope. IT is impossible because they are not all linked into the network. I could build a PBX in my house in a couple of hours and setup two different SIP phones in different locations and make calls and that'd never cross any network the NSA has access to.

Furthermore, as I told him I am involved in setting up CALEA certification so they can TAP calls. It is not a quick process and without it they can't tap calls, and they can't tap them all. They have to do it by specific DIDs due to bandwidth requirements. So the fact the CALEA process even exists is by itself proof they can't record every call.
