*Aha*. Got it. So whether I can, as a recipient, get the CNID of the call originated by the second party depends on whether they can send it to me. That is, *that* part is a capability of the second party, and the only capability the second party's IXC has to provide is bare TBCT. I understand better now, Kevin; thank you very much. I'm in that conference call in about 20 minutes. ;-) Cheers, -- jra -- Jay R.
