AI Call Agents That Actually Work: 26 Best AI Call Agents on the Market

Whether you’re buying phone calls, selling phone calls, or managing the phone call marketplace as an affiliate network, you can do it much more effectively with AI call agents, a technology that is revolutionizing call generation and acquisition right as you read this.

Built on top of a standard IVR system – with Phonexa, you can add AI Call Agents as a block within your IVR without having to change your call flows – AI call agents ensure an unprecedented level of personalization. UX is absolutely human-like, as if your best live operator is handling the call, with no drawbacks. Some calls are handled on the spot, while the rest are connected to the highest-paying business or a relevant sales or customer support rep.

“With phone calls, you’re typically trying to generate a customer that is further down the sales cycle than potentially just a web lead that’s put their data on a website, and you may or may not contact them.” – David Pickard, CEO, Phonexa, during the Unlocking Affiliate Sales with Call Leads, Email & SMS Marketing chat

But then again, not all AI call agents are built effectively. While many software providers have rushed to offer AI call agents, some are still underdeveloped, others lack essential features, and still others struggle with niche-specific conversations they’re supposed to handle.

AI Call Agent Platform Vendors

AI call agent vendors are actually companies that build the software, not just provide it to a business. They develop and license the technology that other, usually smaller companies can use to create their own AI call agents, and then become providers.

Long story short, the software that AI call agent vendors offer is usually a foundational infrastructure you can use “as is” or build your own product on top of. The vendor names speak for themselves: Google, Amazon, Twilio, and so on. These time-tested industries can create new software from scratch, which hundreds of providers then tweak for specific industries and business cases.

Google Dialogflow CX: AI Call Agents with Three Different Levels of Autonomy

Google Conversational Agents is a core call agent technology that uses generative language models to manage conversations in a human-like manner, with full control over conversation flows.

You can integrate Conversational Agents into any device, mobile and web application, IVR, and almost any other existing business solution that can handle over-the-phone conversations. Likewise, Conversational Agents can analyze conversations in real-time, both text and audio, and issue contextualized responses through speech or text.

Important: Google Conversational Agents are an underlying technology for many AI call agents on the market, so you might want to study them thoroughly even if you’re using some other tech. Knowing what Google Conversational Agents can do, as well as their limits, can help find the best application for your business without overcommitting.

When designing conversation flows, you can decide on the degree of freedom you’d like to provide to Conversational Agents by choosing the language model behind: fully generative, partly generative, or deterministic responses, each of which is viable under specific scenarios.

Fully Generative Fully generative conversational flows use Vertex AI language models, enabling fully contextualized responses without any deterministic component. In other words, Conversational Agents base their responses solely on real-time interactions, so every conversation looks different.How to create: Provide natural-language instruction and structured data within a Playbook, the basic building block for generative agents. On top of that, you can use Data stores to parse and analyze your website, documents, and other public and private content.
Partly Generative Partly generative conversational flows combine some level of deterministic control over conversations with the leeway you provide the AI agent so that it can contextualize responses for better UX.How to create: You can design a partly generative conversation flow using Generators and Generative fallback, which is used for issuing responses in cases when the caller’s input doesn’t match the expected intention.
Fully Deterministic It’s worth noting that fully deterministic conversational flows are truly deterministic once the conversational agent identifies the intent of the conversation. Before that, the conversation may not be deterministic, as it varies based on the caller’s data and responses.Once the intent is identified, you can predict the flow with 100% probability, just as if you’re using a standard IVR. Fully deterministic conversation flows reduce risk and may be optimal for conversations where you need full control, compliance, and predictability, such as in banking, healthcare, insurance, and finance.How to create: You can design fully deterministic conversational flows using the Flows feature.

Conceptually, Google Conversation Flows are similar to ChatGPT, except that the logic isn’t necessarily deterministic – you can choose the degree of freedom. Conversational Agents can handle voice calls and live chats and be integrated with your CRM, IVR, or ticketing system.

For supervisors and administrators, Amazon Connect enables a comprehensive lead and phone call management infrastructure, where you can review all the details about the customer in question, from the traffic channel to the initiation method (inbound or outbound contact) to the agent that handled the lead, and, for bounced calls, the reason why a specific call was disconnected.

Likewise, you can use Amazon Connect AI to evaluate and improve the performance of your sales reps, like whether they greeted the customer properly, what was the longest time the customer was put on hold, and anything else you’d like to track on the agent side.

With Genesys, you can build conversational agents for multiple marketing channels within an intuitive visual environment that doesn’t require profound technical knowledge. In practice, you use their no-code platform in your contact center to build bots that leverage both real-time data and past conversations to deliver the best user experience via voice and text.

  • Empathetic conversational experiences that mimic human interactions
  • Omnichannel support and personalized customer experiences across touchpoints

Here’s an example of how Genesys AI works:

A customer visits a bank website to inquire about their account balance. The chatbot authenticates the customer and displays the customer’s account balance. Should the customer want to top up their balance, the bot can help them do it without connecting them to a live operator. If, however, the customer prefers a voice channel, a voice bot can be integrated into the conversation, or the customer can be transferred to an agent.

Here’s what an interface for building a voice bot looks like:

For voice conversations, you can add features like prompts, barge-ins, and timeouts, as well as the ability to transfer the conversation to a human agent whenever necessary or upon the user’s request. For better performance, you can train bots on various utterances within a natural language understanding (NLU) training interface and build bot trainers on top of existing bots.

Here are some statistics across companies that have implemented Twilio Voice:

  • 90% call accuracy and saving 10 seconds on contact center calls for Marks & Spencer
  • 99.8% decrease in customer call-back time, with around a 2-week launch time for St. Luke’s
  • 60% of pre-qualified online leads for Trulia

Twilio Voice supports both inbound and outbound phone calls, enabling branded calls to increase response rates and preventing robocalls through verification signals. Likewise, you can track your phone number’s reputation with the Voice Integrity feature.

OpenAI Voice Agents: An SDK to Create Context-Aware Voice Agents

With OpenAI being the most well-known generative AI technology by far, you can use their API and Agents SDK to build voice agents for a wide range of tasks, from simple customer support to flexible, open-ended conversations – just like ones you can conduct with ChatGPT.

The process of building an AI voice agent with OpenAI is quite simple:

  1. First, you build an agent workflow with their Agent Builder, which provides templates for popular conversation flows, and connect it to OpenAI LLMs, such as GPT-5 or the latest available model at the time of deployment.
  2. Second, you enable access to third-party services with tools and guardrails, and also provide knowledge and memory with vector stores, file search, and embeddings.
  3. Last, you can set up complex conversational flow logic with logic nodes – like how different agents handle different scenarios, work together, and when the user should be transferred to a live operator – or even write your own code using the software development kit.

 

You can use either a pre-determined chained architecture to create structured, predictable workflows with full control and high transparency, or you can use a more advanced speech-to-speech architecture that issues responses based on the caller’s input, including intent and emotion.

What Are AI Call Agents?

Under the hood, AI call agents are conversational algorithms that can recognize and analyze human speech, return contextualized responses, and qualify callers to a matching external business or an internal sales or customer support operator.

A simple and effective way to think of AI Call Agents is that they are ChatGPT for business phone calls – a technology that can handle almost any type of request, be trained to handle industry-specific contexts, and self-learn.

AI call agents are the next step beyond an IVR system, which previously could process customer calls only in a predetermined way through a pre-scripted branch of options, like Press 1 for Sales, Press 2 for Customer Support, Press 3 for Billing and Payments. AI call agents add a whole new layer of quality on top of that, ensuring a sublime UX while allowing you to collect more insights into the calls without overwhelming them with repetitive or irrelevant questions.

How Can AI Call Agents Improve Lead Generation?

For enterprise-level publishers and larger affiliates focused on phone calls, AI call agents can be an absolute game-changer. Through real-time analytics, AI call agents can help qualify calls most accurately to match advertisers, so you get the highest price for the call you’re selling while establishing a reputation on a reliable and high-quality phone call source.

With AI call agents, generating phone calls is easier and cheaper. AI algorithms can quickly learn from collected data and self-improve to handle different types of conversations more effectively, resulting in more conversions and sales.

No less importantly, AI call agents effectively protect you from submitting low-quality, irrelevant, and fraudulent calls to the network or wherever you direct your calls. For example, AI call agents can analyze the caller’s speech patterns and keywords and compare this data with historical data, disqualifying risky calls or flagging them for manual verification.

How Can AI Call Agents Improve Lead Acquisition?

AI call agents are a transformative technology for companies buying phone calls, improving user experiences, and increasing the cost-effectiveness of acquisition. With AI call agents, you can process thousands of inbound phone calls daily without sacrificing quality and – most importantly – qualify and verify callers before you’ve bought them, rejecting or flagging risky calls.

Here are the main benefits of AI call agents for call acquisition:

  • Ability to handle an almost unlimited number of concurrent calls
  • Contextualized responses based on the conversation flow and historical data
  • Real-time phone call qualification and fraud prevention

Since AI call agents understand most aspects of the conversation from intent to keywords – over time, they may surpass human agents in call processing quality and accuracy, at least for simpler requests such as balance checks, appointment bookings, and other transactional requests. Likewise, even for calls transferred to a sales rep – likely the majority of sales calls – AI call agents can issue real-time prompts to the agent, giving them a head start in the conversation.

In a nutshell, AI call agents improve almost every aspect of call processing while only costing a fraction of what you would spend on manual call processing. But then again, AI may not be there yet to make sales, so you still should have a knowledgeable agent at the crux of the caller journey.

Get Your Performance Marketing Platform for Unmatched Call & Lead Management

At Phonexa, we’re solving one of the biggest marketing challenges affiliates, advertisers, and affiliate networks face – the need to jump through hoops and switch software products to cover their campaigns fully. With our performance marketing platform, you get two core modules: Call Logic for intelligent call tracking and routing and LMS Sync for automated lead management. 

Additional plug-ins such as AI Call Agents, iClear, iClaim, and Managed Services expand the platform’s capabilities to enhance compliance, streamline workflows, and fuel intelligent growth.

“There was a study by Forester on phone calls, and they found that calls convert 30% faster than web leads, and callers spend 28% more with a 28% higher retention rate. So that’s pretty much an exponential growth number. If you’re going to go and spend a million dollars on PPC or media buying or whatever, it’s evident that you’re better off trying to spend that money to generate calls than web leads.”David Pickard, CEO, Phonexa, during the Pioneering Pay-Per-Call Excellence webinar

In practice, this means you can synergize lead and phone call campaigns across marketing channels. For example, if an inbound call happens to be on a DNC list, you might also want to remove them from your email list. On the other hand, for bounced calls, you may re-engage them with an email follow-up, taking full advantage of free data flows between our systems.

 

Here are the eight proprietary solutions you get at a single price:

LMS Sync Lead tracking & distribution software
Call Logic Call tracking & distribution software
E-Delivery Email & SMS marketing software
Cloud PBX Cloud phone system
Lynx Click tracking software
Opt-Intel Suppression list management software
HitMetrix User behavior recording & analytics software
Books360 Automated accounting software

Frequently Asked Questions

What can AI call agents do?

AI call agents can do almost everything a real live operator does, from qualifying to nurturing to converting callers. AI call agents imitate human conversations by issuing contextualized responses based on the caller’s real-time input, historical patterns, and preset data, such as how narrowly focused the conversation should be and how deep the answers should be within a particular niche.

How do companies authenticate callers before an AI agent processes the call?

You don’t necessarily have to authenticate callers before an AI agent processes the call because an AI agent itself can do it based on the caller’s responses. The very process of handling a call by an AI call agent costs next to nothing, so it might be best to let it collect data and authenticate and qualify the call more precisely than you would do without having access to real-time conversation data.

As a client with Phonexa, you can also use our verification software, iClear, alongside AI call agents as an additional safety layer. For example, you can compare the information the caller has entered on the form with the data they provided during the call.

How do you implement AI call agents?

As a Phonexa client, you can add AI call agents as a module within your IVR system, all without having to rework your call flows. Then you can train your AI call agents on specific industry data, establish guardrails, like the amount of leeway for conversations, and more.

How much do AI call agents cost?

You get Phonexa’s AI Call Agents for free as part of your subscription plan, and then you only pay for the features you’re using to the extent you’re using them. With our pay-as-you-go pricing model, you only spend money on what matters and only when you use it.
