Communication APIs and telephony pricing
Messaging and voice APIs are pure usage pricing: a fraction of a cent per SMS, email or call minute, with volume discounts that kick in at the millions. Business phone systems in the same list charge per user per month instead, so the two halves of the category barely compare.
