Chalkboard: VoIP vs real carrier (what sells)
Chalkboard risk engines classify numbers as mobile, landline, or internet telephony. Shared VoIP ranges are cheap to burn and frequently blocked — which is why Chalkboard verification fails on TextNow-style apps.
RealNonVoipUSNumber sells carrier-backed non-VoIP inventory for Chalkboard. Fresh lines per order reduce reuse flags, and pay-per-success billing keeps Chalkboard OTP costs predictable when you scale.
