Connect AWS Bedrock Claude to IntelDialix voice agents

How it works

How information moves between a live phone call and AWS Bedrock Claude.

1. 01

   A call reaches your agent

   A caller dials a Twilio or SIP number assigned to the agent, or the agent places an outbound call from a campaign.

   Twilio / SIP number → IntelDialix agent

2. 02

   The agent uses AWS Bedrock Claude mid-call

   When the conversation needs data, the agent runs a custom tool: an HTTP request to AWS Bedrock Claude with the details it has collected.

   Custom tool → AWS Bedrock Runtime InvokeModelWithResponseStream

3. 03

   The call ends with a record

   IntelDialix keeps the recording, transcript and post-call analysis for the conversation in your call history.

4. 04

   AWS Bedrock Claude receives the result

   A signed webhook delivers the call event to your AWS Bedrock Claude endpoint, and is retried automatically if the delivery fails.

Example

// Verify an IntelDialix webhook before trusting it in AWS Bedrock Claude.
// Header: X-Dialix-Signature: t=<unix seconds>,v1=<hex>
// where v1 = HMAC-SHA256(secret, "<t>.<raw request body>")
import crypto from 'node:crypto';

export function verifyDialixWebhook(rawBody, signatureHeader, secret) {
  const parts = Object.fromEntries(
    signatureHeader.split(',').map((kv) => kv.split('='))
  );
  const expected = crypto
    .createHmac('sha256', secret)
    .update(`${parts.t}.${rawBody}`)
    .digest('hex');
  const valid =
    typeof parts.v1 === 'string' &&
    parts.v1.length === expected.length &&
    crypto.timingSafeEqual(Buffer.from(parts.v1), Buffer.from(expected));
  const fresh = Math.abs(Date.now() / 1000 - Number(parts.t)) < 300;
  return valid && fresh;
}

// Body: { "event": "call.completed", "payload": { ... }, "timestamp": "..." }

Check the signature before acting on an event in AWS Bedrock Claude. The secret is the one you set when you add the webhook in IntelDialix settings.
