I’ve just deployed something similar to this via Telin. I’m sure others can do it too. They have an automated system that verifies your ownership/permission to use a phone number, and from then on, you can use it and get either B or A attestation. The most common interpretation of the current regs is that this is the only way you can send off-net CLID in the future. If you want to have a live conversation about this I’m open to a call. It’s something I’ve been doing since the 90s and constantly fighting the changing landscape on CLID.
If you’d like to talk to someone at Telin I can make an intro. Great people, solid service.
