Where the vendors put the same words

• Twilio's voice docs include a page titled Trusted calling with SHAKEN/STIR, and the voice navigation lists SHAKEN/STIR overview and onboarding beside Voice Integrity.
• Bandwidth's voice page says its STIR/SHAKEN APIs are for managing regulatory compliance, in the sentence that opened.
• The same Bandwidth page says a per-query service provides the caller name on VoIP calls in the United States and Canada.
• No attestation fee, no letter-to-price table, and no certificate bundle were read on those pages.
• Caller ID spoofing remains the problem the Wikipedia article names. A vendor menu does not replace the A, B, and C definitions.
