- What it measures
- An illustrative sum that combines two vendors' published figures to show the effect of a real phone line. It is not a quote from either vendor.
- How it is calculated
- $0.11 (Retell example, telephony at $0.00) + $0.0140 (Twilio US outbound) = $0.124 per minute
- What it does not show
- Mixing a calculator example with a list price. Real totals depend on the models, the call length, the tools used, and taxes.
