Clear the overflow queue for every client
Each call ends with a defined outcome, like a policy question answered, an order tracked, a warranty case opened, or a callback logged.
The agent loads the greeting, hours, and policies for the number dialed and answers from that client's playbook.
The agent finds the order in the client's system and tells the caller where it is and when it arrives.
The agent reads the client's warranty summary, takes the order number and the problem, and opens a case after the caller says yes.
When the client's team is closed, the agent saves the reason and the best number to that client's callback queue.
Contact center AI for the calls your floor can't reach
What is contact center AI?
Contact center AI is software that handles or assists customer contacts, from prompts on a rep's screen to bots that take the call. This page covers the last kind. In an AI contact center, a voice agent answers overflow and after-hours calls and passes the hard ones to people.
- Load the client playbook
- Get order status
- Open a warranty case
- Log a callback
- Transfer to the client's team
What happens when one client's calls spike?
Staffing follows a forecast, and queues don't. A carrier delay sends a wave of calls at one client while you're staffed for a normal Tuesday. Extra calls go to the agent right away, so reps keep working the ones they have.

Can someone call me about a return?
Lowmoor's team is back Monday. I can log a callback. What's your name and number?
How does an AI-enabled contact center answer for many clients?
A tool loads the client's playbook from the number dialed, before the agent speaks. A Tidewell Outdoor caller hears Tidewell's name and warranty terms, never a Lowmoor Pet Supply policy. It then reads order status, opens warranty cases and logs callbacks for that client.

Which contact center AI solutions sit alongside this one?
This agent takes no card numbers, and exceptions go to the client's team with the case open. For other jobs, see inbound call handling for spikes, AI IVR for the front door, the auto dialer for outbound lists and roleplay training for new hires.
Resolved on the call
Did the agent resolve the caller's request before the call ended, without a transfer?
What the floor gets from AI contact center solutions
Workforce managers and client leads tend to ask the same things. Can it hold a spike, can it keep clients apart, and can I prove what it did.
Overflow stops turning into hold time
When one client spikes, extra calls go to the agent right away. Your reps keep working the calls they already have, and the queue board stays readable.
An AI contact center platform with a playbook per client
Greeting, hours and policies load from the number dialed. Adding a client means writing a playbook and connecting its systems, with no shift to retrain.
How contact center AI improves efficiency on repeat calls
TW-6012 gets a delivery date in under a minute. A broken zipper gets a warranty case number. Neither call needs a rep to touch it afterward.
Closed clients still get their callbacks
If a client's team is out until Monday, the agent saves the reason and the best number to that client's own callback queue.
AI contact center software that reports client by client
Every call is recorded, transcribed and scored, so an account review can show which requests resolved and which transferred for each client.
Exceptions stay with the client
The agent won't bend a policy or take a card number. A caller who wants an exception transfers to that client's team, who pick up with the case open.
Speech for callers who have already waited
Contact center AI software gets judged in seconds, since an overflow caller has often sat through hold music. Cartesia's speech models keep the exchange quick and take interruptions in stride.

Catches order numbers read aloud
Callers read TW-5521 in pieces and correct themselves halfway. The agent waits through the pauses and picks up cleanly when they cut in.
Playbook first, then the tools
Choose the LLM, then give it the tools that load the client playbook, read order status, open a warranty case and log a callback.
Fits the account, in their language
Choose from the voice library to suit the brand on the line. Callers can stay in their own language, since agents speak 44.
Voice agents, extra seats or a deeper IVR tree
When queue times slip, an AI powered contact center is one of three fixes that usually reach the budget meeting. They solve different parts of the problem.
| Cartesia agent | Added seats | IVR menu | |
|---|---|---|---|
| A sudden spike | Calls run at the same time | Only as fast as you can schedule people | Sorts calls, but the queue still builds |
| Finishing an order status call | Yes, from the client's order system | Yes | Sometimes, if the tree can read order data |
| Off-script exceptions | Transfers to the client's team | Yes, with judgment and authority | No |
| Taking on a new client | Write a playbook, connect the tools | Training time for every rep | Usually a new tree and new recordings |
| Callers in other languages | Speaks your callers' languages | Depends on who is on shift | Often a press-2 option for a few |
| QA coverage | Every call recorded and transcribed | Usually a sample of calls | Mostly menu reports |
| Cost shape | $0.03 per minute, with LLM and telephony on top | Hourly or per seat, busy or quiet | Usually a platform fee |

Contact centers FAQs
What is contact center AI, and what can a voice agent do?
Contact center AI is software that handles customer contacts. Here it is a voice agent that answers overflow and after-hours calls in each client's name, tracks orders, opens warranty cases, and logs callbacks. You decide which systems it can use and what it's allowed to do.
Does it plug into our contact center software?
Yes. The agent connects to your contact center platform and each client's order and case systems through tools you configure.
Can AI handle voice calls in a contact center?
Yes. This agent picks up the number each client's customers dial, talks with the caller, and transfers to a person when needed. Every call is recorded and transcribed.
Can one agent answer for many clients?
Yes. The agent loads the playbook for the number dialed, so each caller hears that client's name, hours, and policies.
Can the agent take after-hours calls?
Yes. The agent answers 24/7 and logs callbacks to each client's queue when their team is closed.
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.
Can we support calls in different languages?
Yes. Cartesia agents speak 44 languages, so callers can talk to the agent in their own language.
How does an AI contact center determine caller intent?
From what the caller says. The LLM behind the agent reads the request in the caller's own words and, with the client's playbook loaded, picks the next step, such as reading order status or opening a warranty case. If the request is unclear, the agent asks. If nothing in the playbook covers it, the call goes to the client's team.
How does contact center AI improve efficiency?
It takes repeatable calls out of the queue. Order status, policy questions and warranty cases finish with the agent, so reps spend their time on exceptions. Because calls run at the same time, a spike doesn't need extra seats that day. The gain depends on your call mix, so score every call and compare.
What is an AI contact center?
An AI contact center is one where software takes on part of the customer contact work. Here that means a voice agent that answers overflow and after-hours calls in each client's name, finishes order and warranty requests, and transfers exceptions. Your reps stay on the calls that need them, and you decide what the agent may do.
How to automate a contact center with AI without losing control?
Start with the calls that repeat, such as order status and policy questions. Write a playbook for one client, connect its order and case systems through tools you configure, and send only overflow to the agent. Read the transcripts, score each call, then widen what the agent takes. Exceptions keep going to people.
How much does a contact center voice agent cost?
You pay only for the calls the agent takes, at $0.03 per minute of call time, so overflow you don't send costs nothing in agent time. LLM usage is billed separately. A Cartesia phone number adds $0.014 per minute, or nothing if you bring your own Twilio account or SIP trunk, which suits a center that already runs its own carrier. The free plan includes $1 of agent calls a month for a first test. See pricing.
