AI Call Center Agents, Built on Your Phone System and CRM.

An AI call center agent is a voice program that answers or places phone calls for a call center. It talks with the caller in plain speech, looks things up in the center's own systems, completes routine tasks such as an order status check or an appointment change, and passes the caller to a human agent when the call needs one. FactoryJet builds custom ones on the phone system and CRM (customer record system) a center already runs, and supports them after launch.

Five jobs cover most of it. Answering routine inbound service calls. Taking overflow calls when every human agent is busy, and calls that arrive after hours. Placing outbound reminder and follow-up calls to people who agreed to be called. Writing the call summary and updating the CRM after each call. Handing the caller to a person with the notes attached, which call centers call a warm transfer. Contact center products also sell tools that coach human agents during a call, which is a different product from a voice agent.

Yes. Every contact center product we checked for it on 11 Oct 2026 lists an AI agent of its own. Genesys Cloud includes virtual agents from its first plan, Talkdesk sells Autopilot, RingCentral sells AIR Pro, and Five9, Dialpad and Aircall each list AI agents. That is six vendors out of six. The open question for a center is which calls to hand over first, and whether the vendor's built-in agent can reach the systems those calls depend on.

No. FactoryJet is a services company. We design, build, implement and support a custom AI voice agent for one call center at a time, on the phone system and CRM that center already uses. You own what we build: the call flows, the prompts, the connectors and the code. If a ready-made contact center product would do the job, we say so on this page and on the scoping call, before you spend anything with us.

Team size and the phone system behind it. An AI receptionist answers the main line of a small office and books the appointment. An AI call center agent works inside a center with a team of human agents, queues, a contact center platform and supervisors. It has to transfer into the right queue and write notes the next agent can use. FactoryJet builds both. Small offices should read our AI receptionist page at factoryjet.com/services/ai-receptionist.

It depends on where your calls already live. If your center runs Genesys Cloud, Five9, NiCE CXone or Talkdesk and the calls you want handled are standard ones, that vendor's built-in agent is the first thing to test, because it is already inside your platform. A custom agent is the better choice when the call depends on a system your platform has no connector for, or when you run two phone platforms and want one set of call rules across both. A fair ranking needs your call recordings, which is why scoping starts there.

Buy the product when four things are true. Your contact center platform sells its own AI agent. The calls you want handled are common ones, such as an order status check or a password reset. The answers live in systems that platform already connects to. You want one vendor contract and one support desk. In that case a custom build adds work you do not need, and your platform's own agent is the sensible first step. The list prices we read on 11 Oct 2026 are in the table on this page.

A custom build fits when the call cannot be finished without data from a system your contact center product does not reach, such as a custom ERP or an in-house order system. It also fits when your call rules are your own (who may change a delivery address, which accounts go straight to a named person) or when you run more than one phone platform. With a custom build you own the call flows, the prompts, the connectors and the code.

We could not find a public count we trust, so here is what we measured. In nine Google searches for AI call center terms on 11 Oct 2026, we counted the contact center platforms on each first page. Genesys appeared on four, and NiCE, Salesforce and Aircall on three each. That shows who ranks, which is a different thing from who has the most customers. Other contact center platforms whose pricing pages we read that day include Five9, Talkdesk, RingCentral RingCX, Twilio Flex and Amazon Connect. Their list prices are in the table on this page.

Yes. Each client program gets its own call flows, its own hand-over rules and its own connection to that client's systems, while the phone connection and the reporting are shared. That keeps one program's rules out of another program's calls. The scoping call covers how many programs start first and who approves each script. We also build white-label for agencies and outsourcers.

Yes. A voice agent can place outbound calls as well as answer inbound ones: appointment reminders, delivery windows, payment-due notices, and a follow-up after a service visit. In the US these calls fall under federal calling rules, because the FCC ruled on 8 February 2024 that AI-generated voices count as artificial voices under the Telephone Consumer Protection Act. So the list of who may be called, and when, comes from your consent records and your own legal counsel. We build the agent to follow the policy you give us.

No. An AI voice on a call is legal in the US, but it is regulated. On 8 February 2024 the FCC ruled that calls made with AI-generated voices are artificial voice calls under the Telephone Consumer Protection Act, effective immediately. FCC rules require prior express written consent before telemarketing calls that use an artificial voice, and bar telephone solicitations to homes before 8am or after 9pm local time (47 CFR 64.1200). This is a summary of public rules and is not legal advice. Your counsel sets your calling policy.

Yes. Overflow means calls that arrive when all your agents are on other calls. Your phone platform sends those calls to the voice agent the same way it would send them to another queue. The agent handles the call types you approved and passes the rest back into your queue with a note, so the next agent does not ask the caller to repeat it. Many centers aim to answer 80% of calls in 20 seconds, the traditional service level according to Call Centre Helper. Overflow is about the other 20%.

After your team logs off, the platform routes calls to the voice agent. It finishes the calls it is allowed to finish, such as an order status check or a booking. For anything else it takes the details, tells the caller when a person will call back, and opens a ticket or callback task in your CRM so the morning shift starts with a list. If you have an on-call person for emergencies, the agent can transfer those calls to that phone using the rules you set.

Calls that need a person's judgment or carry real distress. A caller disputing a charge, reporting a safety problem, asking for medical or legal advice, or closing an account after a death in the family should reach a human agent quickly. So should any caller who asks for a person. We write these as hand-over rules before launch, with your supervisors, and the agent follows them on every call. Gartner's survey of 5,728 customers found the top worry about AI in customer service is that reaching a person gets harder.

A warm transfer hands over the caller and the notes together. The agent tells the caller it is bringing in a person, writes a short note (what the caller asked and what was already done), then transfers the call into the right queue or to a named person. The note reaches the human agent through the phone connection itself or on the CRM record that opens with the call, depending on your platform. The caller does not repeat the story.

Yes. The voice agent takes the routine calls you assign to it, and your people take the calls that need judgment or the authority to make an exception. A Gartner survey of 5,728 customers (December 2023, published 9 July 2024) found 64% would prefer companies did not use AI in customer service. Their top concern was that it becomes harder to reach a person. A center that keeps a fast route to a human agent answers that concern.

Yes. We build the agent to say so at the start of every call, along with your company name. FCC rules for artificial voice messages already require the business to identify itself at the beginning of the message (47 CFR 64.1200(b)). Beyond the rule, callers should know what they are talking to, and that they can ask for a person at any point in the call. Any caller who asks for a person gets one.

A short note in the layout your team already uses. A typical one has the caller and how they were matched to an account, the reason for the call, what the agent did, the outcome (answered, booked, transferred or callback promised) and any follow-up owed. It is saved to the contact or ticket in your CRM when the call ends, with the transcript linked. Your supervisors decide the fields, because they are the ones who will read the notes.

Any platform that can pass a call over SIP, the standard way phone systems hand calls to each other. Vendor documents we read on 11 Oct 2026 show the routes. Genesys Cloud offers BYOC Cloud trunks and an Audio Connector that streams call audio to a third-party voice bot. Amazon Connect transfers calls to queues or outside phone numbers through quick connects. Twilio can transfer a call back to a company's own SIP system. FactoryJet builds on Twilio or Telnyx and confirms the route for your platform during scoping.

Any system with an API, which is the doorway software offers to other software. FactoryJet builds HubSpot integrations and has worked on Odoo, NetSuite, SAP Business One, ERPNext and custom ERPs, so an order status call can read the live order and a booking call can write the appointment. For every system in scope, we read its API documents during scoping and put in writing what the agent will read and what it will change.

No. The voice agent is added beside the platform you have. Your platform keeps the phone numbers, the queues, the human agents and the reporting. It sends chosen calls to the voice agent and receives transfers back, the same way it would with another queue or an outside number. Your human agents keep the desktop they know. That is the main reason to build on your own phone system and CRM.

Yes. You own what we build: the call flows, the prompts, the connectors to your systems and the code. It is built for your center alone, and you do not rent it from us. FactoryJet stays on to support it, and we keep managing the servers, AI models, APIs and maintenance so your team does not have to. If you later want another firm to take it over, the work is yours to hand them.

It depends on whether you buy a product or have an agent built. Ready-made contact center products list seat prices: Genesys Cloud CX $75 to $240 per user a month, NiCE CXone $110 to $249 per agent, Talkdesk $85 to $225 per user, and Five9 $119 or $159 a seat with a 50-seat minimum (vendor pricing pages, 11 Oct 2026). A custom voice agent is a one-off build, which development firm Kanopy Labs puts at $15,000 to $200,000 or more (April 2026). FactoryJet quotes the build and the ongoing support as fixed prices in writing after a short scoping call.

For a custom build, development firm Kanopy Labs gives three bands (27 April 2026): $15,000 to $40,000 for a simple agent that routes calls and answers common questions, $40,000 to $100,000 for an agent with multi-turn conversation and CRM integration, and $100,000 to $200,000 or more for a multilingual enterprise agent. ProductCrafters puts custom AI agents of all kinds at $5,000 to more than $180,000. These are market ranges for the build. FactoryJet quotes its own price in writing after a short scoping call.

FactoryJet does. We keep managing the servers, the AI models, the phone and API connections and the maintenance, so your team does not have to. That includes reviewing transcripts with your supervisors and adding call types when you are ready. We quote the build and the ongoing support as fixed prices in writing after a short scoping call, so you know both figures before you commit.

The time depends on how many call types go live first and how many systems the agent must read or update. One call type on one phone platform and one CRM is the shortest route, and each extra system adds integration work. We put the timeline in writing with the fixed price after scoping. Go-live starts with overflow or after-hours calls, then widens once your supervisors are happy with the transcripts.

On a private phone number first. Your own agents and supervisors call it the way customers do, with interruptions and the awkward questions your center gets. They read the transcripts, mark what was wrong, and we fix it. The agent then goes live on a narrow slice, usually overflow or after-hours calls for one call type, and widens when your supervisors sign off. Before a contract, we can show a working demo agent built on your own call scripts.

It is a service level target: answer 80% of calls within 20 seconds. Call Centre Helper, an industry publication, calls it the traditional service level and notes that many centers now aim for 90% in 15 seconds. The target says nothing about how long the remaining callers wait. A voice agent on overflow is one way to shorten that wait, because it picks up calls that would otherwise sit in the queue.

Four parts. Speech recognition turns the caller's words into text. A language model works out what the caller wants and decides what to say or do. Speech synthesis turns the reply into a voice. A phone connection carries the audio both ways. Services such as Twilio ConversationRelay handle the speech parts so a developer can focus on the logic, per Twilio's documentation. In a call center the larger share of the work comes after that: connecting to your CRM, writing the hand-over rules and testing with real calls.
