AI Phone Agents Compared 2026: Price per Minute, GDPR and What Actually Matters When Choosing a Provider

In short: In 2026 AI phone agents differ less in how they sound than in three things: where calls are processed, how you are billed and whether you need a developer team. Developer platforms such as Retell, Vapi and Bland charge between $0.07 and $0.31 per minute according to their own pricing pages, often with telephony and engineering time on top. Ready-made products such as Goodcall, fonio and EchoCall sell plans. EchoCall costs €0.30 per minute, so it is not the cheapest provider per minute, but it runs on servers in Frankfurt and Karlsruhe and needs no programming.

Last reviewed on 9 October 2026. EchoCall speaks more than 30 languages and costs €0.30 per minute within a plan. WhatsApp is currently not part of what you set up yourself in the EchoHub. Today the EchoCall chat agent runs on your website, with handover to your team. We read the other providers' prices on their own pricing pages on 6 October 2026 and checked Goodcall's prices and Vapi's EU region again on 9 October 2026.

Three kinds of provider

If you search for a comparison of AI phone agents, you find providers that barely compare. It helps to sort them into three groups before you put prices side by side.

Developer platforms. Retell, Vapi and Bland are toolkits for phone agents. You get an API, choose the language model, voice and telephony, and pay per minute. That is cheap and flexible, but it assumes someone builds, tests and runs the agent. All three are US companies.

Enterprise platforms. Parloa and Synthflow sell to larger contact centres. Synthflow states that enterprise contracts start at $30,000 a year. [4] Parloa publishes no amounts and only says that voice is billed per minute and chat per interaction. [5] Here you buy a project with consulting, integration and a contract, not a self-service account.

Ready-made phone agents. Goodcall, fonio and EchoCall are aimed at businesses without a developer team. You set up the agent in a web interface, add knowledge and a calendar and forward your number. Billing is per plan or by the number of callers.

The group often decides your costs more than the per-minute price. A toolkit at $0.10 per minute gets expensive when your developer spends two weeks building on it and then has to make every later change.

AI phone agent pricing 2026: what providers state themselves

The table shows the list prices the providers published on their websites on 6 October 2026. We have not converted dollar amounts, because the providers bill in dollars and the exchange rate moves.

Three things stand out. First, every provider bills for something different: minutes, callers, a platform fee or an annual contract. Goodcall, for example, counts unique callers and says it never meters minutes. [6]

Second, phone numbers and telephony are not included everywhere. With EchoCall they come on top of the plan price. With fonio the smallest plan includes one number, and each additional number costs €9 a month. [7] Bland says the language model, speech recognition and voice are included in its per-minute price. [3]

Third, a low per-minute price on a developer platform tells you little until you know which language model and voice you will use. At Retell the cheapest and the most expensive configuration are more than a factor of four apart. [1]

Worked example: 500 minutes of calls a month

A comparison only becomes useful when you run it at a volume. We assume a business with 500 minutes of calls a month. That could be 200 calls of 2.5 minutes each from 150 different callers.

Per minute, EchoCall sits at the upper end of the plans in this example. We say that openly. If you only compare per-minute prices and have a developer in house, a developer platform is cheaper.

What the table does not show are the limits of the entry tiers. Bland's Start tier allows 10 concurrent calls and 100 calls a day. [3] Retell includes 20 concurrent calls. [1] And it does not show the hours someone spends on prompts, testing, calendar integration and debugging. With a ready-made phone agent you do that yourself in the interface. With a toolkit it is engineering work.

EU data residency: where are calls processed?

For businesses in Germany and the rest of the EU this is often the first question, and it is often answered loosely.

Retell states in its own documentation that it currently does not operate any services within the European Union. [9] Every call through Retell is therefore a transfer to a third country under Chapter V of the GDPR. That is not forbidden, but it needs a legal basis such as standard contractual clauses and a documented assessment. [14]

Vapi has its own EU region with a separate dashboard. According to Vapi it is available only with the Premier Success Package. On its GDPR page, however, Vapi also says that personal data is processed outside the EU, mainly in the United States, covered by standard contractual clauses. [10]

EchoCall runs its platform on IONOS servers in Frankfurt and Karlsruhe. You will find the data processing agreement and the list of sub-processors on the GDPR page. [11]

One point applies to every provider: hosting in Germany does not automatically mean that every component runs in the EU. Speech recognition, the language model and the voice come from suppliers at most providers. So read the list of sub-processors and check which countries they process in. We have not analysed the data protection documents of Bland, Goodcall, fonio, Parloa and Synthflow in detail. Ask them directly.

Developer or web interface: who builds and maintains the agent?

A phone agent is not something you buy once and forget. It needs a conversation guide, knowledge about your business, rules for transfers and a connection to your calendar or CRM. And it needs someone who improves it when callers ask things nobody anticipated.

On a developer platform that means code and configuration. With a ready-made phone agent it is a form. In EchoCall you upload your knowledge as PDF, TXT, Markdown, CSV or JSON, add individual pages of your website with a re-read interval or have the whole site crawled. During a call the agent can use tools, for example Google Calendar, Outlook, Calendly or Cal.com for appointments and HubSpot or Salesforce for contacts. Zapier, Make and custom webhooks reach further systems.

You can see how quickly that works in the live demo: enter your website address and the demo builds an agent from your public pages in about 20 seconds, which you can call in the browser. No signup needed.

Handover to a human

No phone agent answers everything. What matters is what happens when it gets stuck. In a Gartner survey of 3,566 customers, 87 percent said that a company using generative AI in customer service must offer a way to reach a human. [12]

Check three things with every provider. Can the agent transfer to a phone number? What happens if nobody answers there? And does your team learn what the call was about? With EchoCall the voice agent transfers to a phone number. Chat conversations on your website can be taken over by your team in the Live Inbox.

Language, voice and response time: test them yourself

Many websites quote response times in milliseconds. They are rarely measured under conditions that match your calls. So test yourself, with the same questions for every provider:

1. 20 test calls from a mobile and a landline, at different times of day.
2. Measure pauses: record your test calls and measure the silence between the end of your sentence and the start of the answer. Only compare providers using the same questions.
3. Interrupt: talk over the agent. Does it stop and respond to you?
4. Names, addresses, numbers: have it take down a postcode, a house number and an unusual surname, and check what arrives in your system.
5. Switch language: change language mid-call. EchoCall supports more than 30 languages and detects the caller's language automatically if you switch that on.
6. Background noise: call once from the car or the street.
7. Transfer: ask for a person and check that the call arrives.
8. Appointment: book an appointment and check that it lands in the right calendar.

With EchoCall you can do this in the trial: 30 voice minutes and 30 chat conversations for 14 days, and the credit card is verified with €1.

AI disclosure: required with every provider

Since 2 August 2026, Article 50 of the EU AI Act applies. People who talk to an AI system must be told so, at the latest at the first interaction, unless it is obvious. Under Article 99, breaches can be fined up to €15 million or 3 percent of worldwide annual turnover. [13]

This applies regardless of the provider. The business that deploys the agent is responsible. With EchoCall you write the notice for phone agents into the first message yourself. The editor shows an info box, and the help centre has example sentences. In the chat widget an AI notice appears automatically.

Providers that place and receive calls: what works and what is allowed

Many platforms can answer calls and place them. With outbound calls the real question is not the technology but the law. In Germany, advertising calls to consumers need prior express consent (§ 7(2) no. 1 UWG). For calls to businesses by a person, presumed consent is enough. For advertising with an automated calling machine the law requires express consent in every case (no. 2). [15] Whether an AI agent counts as one has not been decided. Assume that it does.

Calls without advertising, such as a callback the customer asked for or an appointment reminder, are not affected. The details are in AI Cold Calling in 2026, and how to run campaigns in AI Batch Calling 2026. One point matters for the comparison: no provider checks your consents for you. EchoCall does not check consents or match block lists either.

Checklist for choosing a provider

Frequently asked questions

Which AI phone agent is the cheapest?

Per minute, developer platforms are cheapest. Retell quotes $0.07 to $0.31 per minute, Bland $0.12 to $0.14. Among ready-made plans, fonio charges €119 for 1,000 minutes. But calculate with your own volume, with the phone number and telephony, and with the time someone needs to build and maintain the agent. EchoCall costs €0.30 per minute within a plan and is not the cheapest provider per minute.

Which providers process calls in the EU?

Retell says it currently operates no services in the EU. Vapi has an EU region with its Premier package, but according to its own GDPR page it also processes data in the United States. EchoCall hosts its platform with IONOS in Frankfurt and Karlsruhe. With every provider it is worth reading the list of sub-processors.

What does Parloa cost?

Parloa does not publish prices. Its pricing page only says that voice is billed per minute and chat per interaction. You get a figure in a sales conversation.

Do I need developers for an AI phone agent?

For Retell, Vapi or Bland, usually yes, at least for the build, telephony and integrations. Ready-made phone agents such as Goodcall, fonio or EchoCall are set up in a web interface. With EchoCall your website, your knowledge documents and a call forward on your number are enough.

How do I test a provider before committing?

Make at least 20 test calls with the same questions for each provider, record them and check pauses, interruptions, names, transfers and appointment booking. You can test EchoCall with 30 voice minutes and 30 chat conversations for 14 days, and the credit card is verified with €1.

Does the caller have to know they are talking to an AI?

Yes. Since 2 August 2026, Article 50 of the AI Act requires the notice at the latest at the start of the conversation, unless it is obvious. On the phone it rarely is. One sentence in the greeting is enough.
