How the price example is calculated

The current public pricing page lists enterprise contracts from $30,000 annually. $2,500 is that annual minimum divided by 12, not a monthly cancel-anytime plan. No public 1,000-minute quote is supplied. Source

AXL voice usage, number rental and carrier rates are separate from the platform subscription. Included AI credits are shared with other AI work. Your active account settings determine the final voice rate.
