}Register phone numbers with the Free Caller Registry
Submits US numbers to the Free Caller Registry, which feeds the analytics engines used by T-Mobile, AT&T and Verizon for spam labeling (Hiya, TNS, First Orion). Numbers hosted on RevDesk are included free; bring-your-own numbers bill $5/number per calendar month as a Number Registration line item on your invoice, starting when the registry accepts the submission. Requires an authorization attestation — you must be entitled to register these numbers for the business they belong to. Business identity defaults to your workspace’s caller-trust profile; override per-request with business_identity. Async: poll GET /v1/number-registrations or subscribe to registration_submitted / registration_confirmed / registration_failed webhooks. Re-registering an already-live number is free and refreshes it.
