PAT] Pat makes it seem like an international trace is relatively simple, but that is not the impression I received from reading Cliff Stoll's book _The Cuckoo's Egg_. In that case, it was a call being traced from the US into West German. The West German Bundepost would not release the trace information without an official request from the US Legal Attache in Germany. I suspect the UK trace also required prior diplomatic approval and coordination. (BTW, after the book was mentioned several weeks ago in regard to secure telephones, I picked it up and read it. I highly reccommend it for all readers of this list. It deals with the Internet, call tracing, computer security and is a fascinating, true story.)

[Moderator's Note: Any additional difficulties or delays encountered in an international trace are purely from the reasons you give if the telcos do not have an advance agreement. On domestic traces, the agreements seem to be in place. Even the big three competitors, AT&T, Sprint and MCI work together in matters 'of common concern' -- fraud being one such concern shared by all. PAT]
