F.A.Q
Quick answers to common inquiries. Need help? Book a demo for personalized assistance.
Each call is tracked to the nearest second. At the end of each billing cycle, we charge based on your total accumulated minutes. No rounding up per call, no inflated bills.
Once the call is transferred, the AI voice agent fee stops. Only the telephony fee continues for the remainder of the transferred call.
Yes. Billing covers the entire duration of the call because the speech-to-text engine remains active and listening throughout, even during silence.
Invoices are available in the Billing tab after each billing cycle. Make sure to add your company information before the billing date so it appears on your invoice.
You are only charged for connected calls. If a call fails to connect, you won't be billed. For calls that reach voicemail, billing applies only for the duration the AI agent is active on the line.
Every account includes 20 concurrent calls for free. Need more? Additional capacity is $8 per concurrent call per month. Add or remove anytime as your volume changes. Enterprise plans offer custom concurrency starting at 50+ calls.
