When things don't go to plan.

When she can't hear you: She asks you to say it again, and if the line stays bad she passes the call to a person.
When she isn't sure: She transfers you to a person instead of guessing.
When you ask for a human: She hands over with a warm transfer, and the person gets a written summary of the call so far.
When the lead is on a do-not-call list: She doesn't dial: every number is checked against the list before every call.

Questions about voice agents.

What does a call or a document cost?

Carrier minutes and AI tokens are billed by the providers to your own accounts at their published rates. We add no platform fee. Typical: ~$0.03 per call-minute on Ava; cents per document for reading; near zero for on-premise.

Which languages?

Our voice agents speak English and Urdu today, and our invoice reader handles English, French and Spanish. Tell us yours and we'll test it in a Proof Sprint before you commit.

Will it hallucinate, and what happens when it does?

It can, so we build for it. Answers come from your own documents and cite them. When the agent can't find support, it says it doesn't know and hands over to a person: our private search abstained correctly 5 times out of 5 in testing. Payments, database writes and deletions always wait for an approval you set.

Who is liable when it's wrong?

Your contract sets liability, under English law. We also design so mistakes stay small: the agent says it's an AI, hands over when it's unsure, and can't make a payment, write to a database or delete anything without your approval.
