Lately I've been getting calls to my Tmobile cell phone with CNAMs such as Scam Likely and Nuisance Call.  Even without the CNAM I know they are call centers so don't pick up, but I'm wondering who assigns that CNAM?  I'd expect Tmobile to dip the CNAM but doubt the official database would flag the number this way. If it's coming from the call center app it's pretty funny. I don't know anywhere else along the call path it would be changed.

Hi Everyone,

We are looking for an API provider for real-time carrier lookups.
Specifically because we need to determine the Canadian wireless carrier
(Rogers, Bell, Telus, etc.) to know where to direct a text message.

I see Twillio has a real-time API, but it's quite pricy. When I looked at
this about a decade ago, Telcordia used to have monopoly on this type of
data, hoping things have changed.

Thanks in advance.
