Nowadays, if I want to withhold my CLI, I don't send anything. That
works pretty
well. Don't put junk in - I know that I can't call various destinations
over BT if I
use something bogus (like na, or thiscliisaloadofoldbollocks[1]); I get
a 403 Forbidden
back.
Thats very strange for me :-) All TSPs around - if you are "only" end
user - force you to send valid CLIP (From: header) or silently rewrite
it. Some bigger customers (corporations etc.) have "the privilege" to
send whatever CLIP they want because they are directly responsible for
CLIP validity to local Telecommunication Office...
Sorry - what I didn't make clear is that we are connected as a
"carrier" - we treat our end users
