Justy a note, you need to create an OpenCNAM account and fund it if you do not have one.

I recommend OpenCNAM because it is generally cheaper than your carrier CID charges.
If you recall from the VoIP.ms setup, they charge $0.008 per lookup.

OpenCNAM is half that at $0.0039 per lookup. https://www.opencnam.com/pricing
