Correct sip URL to ring VOIPo?

Does the VOIPo Express numbers do CNAM and is there a charge?

Since Express is just a forwarding service it just passes on the CNAM that came on the first leg of the call. Those calls are literally just forwarded on and it's more of a "bridge" between the original leg and the final leg. We don't handle audio for them or really change these calls are at all. Literally just an intermediary.
