Hello Roman,

In my opinion, US Carriers are unlikely to accept vanilla RCD data because of the lack of defined KYC.  RCD is a very good vehicle for delivering the RCD, but it depends upon implicit trust of the originating service provider. “Vanilla” RCD offered like this to terminating service providers gives no assurance to the terminating service provider that the originator performed any specific KYC.

CTIA’s BCID is based on RCD but details an ecosystem with specific KYC requirements. Participating in this ecosystem will allow for the delivery and native presentation of RCD.

It’s worth noting that without a defined ecosystem for RCD such as BCID, RCD provides little (trust)  benefit over traditional CNAM other than the fingerprints of the originating service provider for enforcement purposes.

You don't often get email from [e-mail]. Learn why this is important<https://aka.ms/LearnAboutSenderIdentification>
In my day job, I see a lot of robocalls coming through the LEC local switches as TDM, as local re-origination with spoofed ANI.

I would also love to sign Rich Call Data with my SPC token and not have wireless carriers discard this data. If I provide the information about my customer, I am unsure why I need to pay someone else to sign this information.

It wont . You mean the legacy TDM/SS7 crap…this is the beginning of mandating all SIP in the US realtime US voice network as the British have done.

I would not want to own a Tandem Access network.

The US industry is pretty clear on this.  You only need to read the FCC 17-97 docket at the FCC ECFS website to understand where the players actually are.

This again is my day job.
