A full-duplex AI phone agent that listens while speaking

Famulor launched a full-duplex AI phone agent that listens while speaking, handling inbound calls, outbound campaigns, and follow-ups across WhatsApp, email, SMS, and a website widget from a single contact record. The agent supports 45 languages and 23 countries, offers a catalog of over 10,000 voices, and connects to nine CRMs including Salesforce, HubSpot, Pipedrive, and HighLevel. Famulor said the platform requires no code, uses a visual flow editor with 9 node types, and redacts personal data before transcripts are written to storage.

The campaign dials in parallel and keeps to the hours you set. Do-not-call suppression is checked before the first ring.

campaign = quote requests · voice = Marcus · dnc = clear Answering-machine detection confirmed a real person. A data collection node in the flow captured her ZIP code and coverage type. Recording started only after she agreed to it.

reached = true · consent = granted · fields = 2 WhatsApp runs on Meta's Cloud API, so the same agent keeps the thread going in writing: coverage summary, her questions answered, callback set for 6pm. An SMS reminder goes out before the slot.

channel = whatsapp · callback = 6:00 pm · sms reminder = queued The agent booked straight into the native scheduling engine. Cal.com, Calendly and eTermin work the same way, and a Google Meet link is generated with the invite.

callback = on time · booked = thu 10:00 · calendar = native Post-call analysis extracts the outcome, the sentiment and the custom fields you defined. An automation writes them onto the CRM record and posts the recap to Slack.

sentiment = positive · fields = 6 · automation = crm + slack

One contact record. One agent. Voice, WhatsApp and the calendar in a single thread.

No engineering team required. One agent answers inbound calls, dials outbound campaigns and follows up over WhatsApp and email.

Step 01

Write the goal in plain language and pick a voice from a catalog of over 10,000, in any of 45 languages. Shape the call in the visual flow builder: 9 node types, including data collection, DTMF menus and warm transfer. No code.

Step 02

Upload PDFs, DOCX and 10 more text formats, or point the crawler at your website for up to 500 pages with automatic re-sync. Connect Cal.com, Calendly, eTermin or the built-in scheduler so the agent books straight into a real calendar.

Step 03

Provision a number in one of 23 countries, or import your own SIP trunk from Twilio, Telnyx or Vonage. The same AI voice agent answers inbound calls and runs outbound calling campaigns.

Step 04

Run scripted test conversations against the agent and let an LLM judge the answers. Once live, listen in, whisper, barge in or take the call over yourself.

Every assistant is scanned for impersonation and fraud patterns on save. Consent and do-not-call suppression are always enforced, call recording only starts once the caller agrees, and transcripts are redacted for personal data as they are written.

Hi — I'm Milian

What would you like to build?

Bookings land in the calendar your team already uses. Contacts come from your CRM. After the call: native automations, or the REST API and MCP, if you build it yourself.

Real slots land in the native scheduling engine, Cal.com, Calendly or eTermin. The agent creates the booking itself, with a Google Meet or Microsoft Teams link generated for the invite.

Pick a vertical. The same agent answers inbound calls, runs outbound campaigns, and picks up the thread on WhatsApp and email. In 45 languages.

Calls Handled

What teams check before they go live: how the agent answers, what it connects to, and where the data sits.

You design the conversation in the visual flow builder, no code, and point a phone number at it. The agent answers every inbound call, replies from your knowledge base, books appointments and collects the details you define.

More on pricing, security and white-label in the full FAQ.

Plus outbound SMS for follow-ups and reminders.

01 · Voice

Point a phone number at your AI receptionist and every call gets picked up. Outbound campaigns dial in parallel inside your calling windows, detect an answering machine and drop a voicemail. Warm or cold transfer to a human when the call needs one.

02 · Messaging

WhatsApp runs on Meta's Cloud API: free-form replies, approved templates, business profile and WhatsApp voice calls. Telegram, Slack, Facebook Messenger, Microsoft Teams, Google Chat and X are real provider integrations. Discord through its interactions API. Outbound SMS for follow-ups, reminders and notifications.

Messaging

Delivery update on WhatsApp

Follow-up on WhatsApp. SMS reminder before the appointment.

03 · Email

Email is a full AI channel here, not a notification. The agent keeps real threads, drafts and sends replies, analyzes the thread for sentiment and outcome, and steps aside the moment a human takes over.

Re: invoice #10482 — double charge

Hi Mira,

Thanks for flagging this. I checked Stripe — the second charge on 12 Mar was a retry after a soft decline, then both settled.

I've issued a full refund for the duplicate (€49). It should land in 3–5 business days. Reply here if it doesn't show up.

04 · Web widget

Embed one widget and visitors choose: talk to the AI voice agent or type instead. The same knowledge base as your phone line. An origin allowlist so it loads on the domains you list.

05 · CRM & automations

Contacts pull in from nine CRMs: HubSpot, HighLevel, Salesforce, Pipedrive, Close, Zoho, Attio, Keap and Twenty. From there the native automation engine takes over: 93 triggers and actions across 22 connected services push outcomes, transcripts and bookings onward.
