  title: Regal Branded Phone Numbers API
  version: '1.0'
  summary: Register, update, and remove branded caller ID and spam remediation entries.
  description: Branded Phone Numbers in Regal control how a tenant's outbound numbers appear on recipients' devices via carrier-level branded caller ID and spam remediation. Each registration ties a phoneNumber to a businessProfileId and a carrierFeatures array describing which features (spamRemediation or brandedCallerId) are enabled per carrier. POST is used for first-time registration only; PATCH is used for partial updates; DELETE removes a registration once all carrier submissions are inactive.
