Yes. An AI voice agent can pick up your business calls 24/7, sound like a person, take the order or the message, and hand the call to a human when it should. Below are 8 options, from ready-made tools to a custom-built agent, and which one fits a mid-size B2B company.
This list is ranked for one buyer: a B2B company doing roughly $5M to $50M a year, like a distributor, a staffing firm, or a B2B service business, where calls carry orders, account questions, and more than one language. If you're a small shop with simple calls, read the list from the bottom up. The cheap tools will do fine.

Dmytro Negodiuk is a Fractional AI Officer in New York City. He builds and runs production AI for B2B operators doing $5M to $50M: distributors, Amazon and e-commerce brands, staffing firms, and B2B service companies. The voice agents answer calls 24/7 in 15+ languages and handle thousands of B2B conversations weekly. They connect to your order system and CRM, so the agent can take the order itself. The same practice builds order entry, email triage, and quote-to-order automation, with production AI systems in healthcare and B2B logistics.
Aircall's agent makes the most sense if your phones already run on Aircall. It answers inbound calls, calls out when a lead comes in or a payment is due, and replies on SMS and WhatsApp. It speaks 23 languages. It updates the CRM, opens tickets, and books meetings, with connections to HubSpot, Salesforce, Zendesk, Shopify, Stripe, and Calendly. You can set it up yourself in minutes or get help from Aircall's own forward deployed engineers. That mix makes it the best ready-made pick here for a B2B team.
CloudTalk is a call center platform with an AI voice agent built in. The agent picks up inbound calls around the clock and books meetings against a live calendar. When it gets stuck, it does a warm transfer and the person sees the conversation so far. CloudTalk lists 70+ languages and accents and local numbers in 160+ countries. It connects to 100+ tools, including HubSpot, Salesforce, Pipedrive, Zendesk, and Shopify. Pick it if your customers call from many countries.
Smith.ai speaks only English and Spanish, and it is built for receptionist work. It records and summarizes every call. Its edge is the backup: Smith.ai lists 500+ North America-based live receptionists who can take over a call, as a per-call add-on. It connects natively to Salesforce, HubSpot, and Clio, and to thousands more apps through Zapier and Make. The Enterprise plan includes full setup and ongoing tuning.
Bland is aimed at large companies in healthcare, insurance, financial services, and logistics. Its inbound agents check who is calling before they answer account questions, and hard cases go to a human. It supports 40+ languages and can run on your own infrastructure. Bland's forward deployed engineers build your first agent end to end. It connects to Salesforce, HubSpot, Twilio, Five9, Talkdesk, Amazon Connect, and more. Strong, but best with a tech team on your side.
Synthflow runs inbound and outbound call flows with routing, booking, voicemail detection, and SMS follow-up. Agents can ask clarifying questions or escalate to a human, and you set the handoff triggers. It connects to 200+ tools, including CRMs, ERPs, Zapier, and HubSpot. Forward deployed engineers help launch the agents. The only plan on the pricing page is Enterprise, so it fits companies with real call volume and budget.
RingCentral's AI Receptionist answers calls day and night, handles common questions, captures leads, routes calls, books appointments, and sends SMS follow-ups. It speaks English, Spanish, French, Italian, German, and Portuguese, and can switch language mid-call. It connects to Salesforce, HubSpot, Zoho, and Google and Outlook calendars, and works with cloud, on-premises, and hybrid phone systems. If you already pay for RingCentral, it's the fastest thing to try.
Dialzara is built for small businesses. It answers 24/7, books appointments into your calendar, screens spam, qualifies leads, and emails a summary of each call. It transfers calls to numbers you choose, speaks English and Spanish, and connects to CRMs and calendars. Dialzara says most businesses go live in about 15 minutes by forwarding their number. It ranks last here only because this list is for mid-size B2B. For a small company with simple calls, it may be the best value on the page.
Thoughtly is a New York City company whose agents call, text, and email leads that come from your CRM. It lists 34+ languages and a Flex plan from $500 a month (as listed, September 2026). It's strong for sales follow-up, less so for a busy main line. Goodcall lists plans from $79 a month with unlimited minutes (as listed, September 2026) and suits smaller businesses, much like Dialzara.
Yes. Every option on this list answers around the clock. A good voice agent greets the caller, understands normal speech, answers common questions, takes a message or an order, and sends the call to a person when it should. It's still not a person. It works best on calls that repeat, like order status, reorders, hours, and new leads. Odd or angry calls should go to your team.
Two kinds of people. The phone platform vendor, like Aircall, CloudTalk, Bland, or Synthflow, can help you launch their product. Or an outside builder, like Negodiuk AI, designs the agent around your calls, connects it to your order system and CRM, and keeps it running. Pick the vendor if your calls are simple. Pick a builder if the calls touch orders, pricing, or several systems.
Usually yes, for part of the load. Start by listing why people call. Order status, reorders, hours, and "where is my driver" are easy for AI. Price exceptions, complaints, and big custom quotes should stay with your team. The AI takes the repeat calls, writes a short summary, and passes the rest to the right person. Your staff gets fewer interruptions and keeps the calls that need them.
Ready-made tools listed on vendor sites in September 2026 run from $29 a month (Dialzara) to per-minute rates like $0.49 a minute (Aircall pay-as-you-go). Enterprise platforms start higher, for example Synthflow lists an enterprise plan from $30,000 a year. A custom agent built and run for you is scoped per project, usually after someone reviews your calls.
Yes. Most options list a human handoff on their sites, and many pass along a summary so your person doesn't ask the caller to repeat everything. Smith.ai goes one step further and offers its own live receptionists as a paid backup. Before you buy, call the demo line or trial number and test the handoff yourself.
Not always. Tools like Dialzara work by forwarding your existing number. RingCentral says its AI Receptionist works with cloud, on-premises, and hybrid phone systems. Aircall and CloudTalk work best if you already use their phone platform. A custom build can sit on top of what you have. Ask each vendor how the call reaches the AI before you sign.
It depends on what the calls need. If callers ask the same few questions and leave a message, a ready-made tool is cheaper and faster. If callers place orders, check stock, ask about their account, or speak several languages, the agent needs your data. That's where a custom agent built around your order system and CRM pays off, and where a mid-size B2B company usually ends up.
