iPhone Calls verified by carrier

[frumpy16]

I just noticed this after installing the new public beta. The calls were from before the install. Is this new?

I've read that some TMO and Verizon beta users have been seeing this in earlier betas. STIR/SHAKEN is slowly rolling out across providers.

The big issue, if I recall correctly, is that all the providers need to implement the standard, so that information flows between the different telcos when a call is initiated.
