Inbound voice agents
Publish a bot to a provisioned number and let it answer. Pick TTS (ElevenLabs or Cartesia) and STT (Deepgram, Azure, or ElevenLabs) so each agent matches the sound and accuracy you need.

Deploy human-sounding agents on real phone lines. Handle inbound conversations and shoot outbound calls from a contact list. Choose languages, voices, and your TTS and STT stack for every bot.

Product
Voice agents built for real phone lines
Design the conversation once. Publish it to inbound numbers, shoot outbound calls, and keep knowledge, tools, and reporting in the same workspace.
Outbound calling
Upload a contact list, map variables, and shoot outbound calls. Agents dial at scale, run the flow you designed, and log every attempt.
Visual flow builder
Compose agent, webhook, and variable steps on a canvas. Attach a knowledge base and HTTP tools so the bot can look up answers and take action mid-call.
Multilingual by design
Configure the languages each agent should speak and switch when the caller does. Pair that with multilingual speech models so you are not locked to a single locale.
Knowledge, tools, and follow-ups
Ground answers in documents you ingest. After the call, workflows can write to Google Sheets, send a calendar invite, or hit your webhook.
Transcripts and analytics
Every voice session is logged with transcript and recording. Review inbound and outbound results, export reports, and track credit usage.
Process
How it works
Build the agent, put it on a number, then answer inbound or dial outbound.
01
Design the conversation
Build
Draw the flow, attach knowledge and tools, and set languages plus your TTS, STT, and LLM providers for that bot.
02
Publish to a phone line
Launch
Deploy to an inbound, outbound, or bidirectional number so the same agent can take calls or place them.
03
Answer or dial the list
Call
Handle inbound traffic automatically, or upload contacts and shoot outbound calls. Review transcripts, recordings, and follow-up workflows after.
Use cases
What teams run first
Start with inbound coverage or outbound dialing—then expand with knowledge, tools, and post-call workflows.
Inbound
Answer every call with your knowledge
Publish a multilingual agent to a number. Callers get answers from documents and sites you ingested, in a voice you chose.
Outbound
Shoot calls from a spreadsheet
Upload contacts, map columns to variables, pick an outbound voice channel, and dial the list immediately or on a schedule.
Sales & ops
Qualify, remind, and follow up by phone
Use the same agent to reach leads, confirm appointments, or collect updates—then log outcomes to Sheets or your own API.
After the call
Automate what happens next
When a conversation ends, workflows can write a row, send a calendar invite, or call a webhook so your team does not re-enter the data.

FAQ
Frequently asked questions
Can agents take inbound calls and place outbound ones?+
Yes. Publish a voice agent to an inbound, outbound, or bidirectional number. Inbound traffic is answered automatically. Outbound calling uses a contact list—upload a spreadsheet, map variables, and shoot the calls.
Which languages do you support?+
Agents are multilingual. You configure the languages each bot should speak, and our speech providers (ElevenLabs, Cartesia, Deepgram, Azure) cover a wide range of languages and accents.
Can we choose TTS, STT, and the language model?+
Yes. Text-to-speech: ElevenLabs or Cartesia. Speech-to-text: Deepgram, Azure, or ElevenLabs. Language models: Azure, Groq, or Cerebras. Set this per bot so quality, accent, and latency match the use case.
How does outbound calling work?+
Upload a contact spreadsheet, map columns to bot variables, pick a published outbound voice channel, and run immediately or on a schedule. Each attempt is logged with transcript and recording.
Can we connect WhatsApp as well?+
Yes. Connect a WhatsApp Business number as a channel, create and sync message templates, and run campaigns to a contact list. Delivery and send records stay in the same workspace as your voice agents.
How do we go live?+
We provision a voice number for your workspace and you publish a bot to it. WhatsApp goes live when you connect a Business number and have approved templates. Book a demo and we will walk through both on your use case.
How does pricing work?+
Usage is billed in credits for voice, WhatsApp, and related services. Share your inbound, outbound, and messaging volume through the contact form and we will send a quote.
