I find it hard to believe a CNAM would be stuck saying "Unknown". Was this a new VOIPo issued number kdonnel?

Worst case they usually say he city and state.

If its a matter of getting your name to display, I understand the difficulty of that. Vonage never supported except in their earliest days (around 2003). If anybody should have clout, it should be a company with over a million customers! Like Brian did, getting an upstream request put in sounds like a good idea.

Brian, does it say your name now, or something generic?

I had outgoing name before my number ported, and it has stayed with it.
My 2nd line just says "Wildwood Fl".

Checking the CID blocking is a good idea, but that would block the Number and Name, not just the name.

What does http://tnid.org show your number belongs to?
My line showing my name is Broadwing Communications Llc - Mi. It used to be XO
My FL number is Level3.
