Customer support FAQs

How is a voice agent different from an IVR menu?

An IVR is the "press 1 for billing" menu. It routes callers to someone who can help. A voice agent understands the request in the caller's own words and resolves it on the call, using the systems you connect and the rules you set.

Can an AI agent take calls for our call center?

Yes. It resolves the calls your policy covers, such as billing errors, account questions and setup help, at any hour, and sends the rest to your team. How an AI call center works.

Can Cartesia work with our existing support stack?

Yes. The agent calls your helpdesk, billing and account systems through tools you configure, and uses the LLM you choose.

How much does a customer support voice agent cost?

Agents are $0.03 per minute through December 31, 2026.

Can an agent hand a caller over to a person?

Yes. The agent can transfer calls to your team, and you control exactly when it does.

How should we measure a support agent?

Evaluate the agent against your key success criteria. For example, you can measure what percentage of calls the agent resolves autonomously, or what percentage of customers stay after asking to cancel.

Can an agent process refunds or change an account?

Yes, once you connect it to your billing and account systems. You decide which refunds and credits it can issue, up to what amount, how callers prove who they are, and when a person must approve.
