How it works
No engineering project required. Most agents go from blank page to first real call in an afternoon.
Write instructions in plain language, choose a voice and add the tools the agent may use.
Call the agent from your browser, read the transcript and refine until it sounds right.
Assign a Twilio or SIP number for inbound calls, or launch an outbound campaign.
Paste your site. In about 20 seconds you get an agent that knows your services, hours and FAQs, and you can talk to it before you sign up.
Four numbers, one honest estimate of the revenue going to voicemail.

IntelDialix is a workspace for building AI voice agents that answer and place phone calls. You write the agent’s instructions, pick a voice, attach a phone number, and IntelDialix handles the calls — with a recording, transcript and outcome for every conversation.
Agents can run on ElevenLabs, Vapi or Google Gemini. You choose the engine per agent, so you can compare voices and latency on real calls without rebuilding anything.
Yes. Connect numbers from Twilio or bring your own SIP trunk, then assign an agent to each number for inbound calls or use it as the caller ID for outbound calls and campaigns.
Every agent has a test call you can run straight from the browser. You hear the voice, see the live transcript and can adjust the prompt before assigning the agent to a real number.
Import contacts from a CSV, choose an agent and a number, and launch a campaign. IntelDialix dials through the list, skips numbers on your do-not-call list, and records the outcome of each call.
Plans start with Starter at $14 a month for one agent, one number and 100 calls. Higher plans raise the limits on agents, calls and phone numbers and add features such as webhooks and API access. A free account lets you explore the dashboard first.
