Kanata (Ontario). Canada. Lines: 11 I worked for the phone company up here in the frozen north for a while and I never heard anything about a 'header' being transmitted down the line. There are some wonderfull things that your central office can do (depending on how new and sophisticated it is) but this isn't one I know about. I am now working on the development of one of the latest C.O.s and again, this "feature" is not on the list. If anyone knows any different please tell me and I will talk to the designers here and get our system updated. Pete
