How to Use OpenClaw for Voice Calls

Prerequisites

• ✓An existing OpenClaw Gateway deployment configured with at least one agent.
• ✓Access to a telephony provider account such as Plivo or Twilio that can connect to external webhooks.
• ✓Network access from your telephony provider to your OpenClaw Gateway so it can deliver Voice Call webhooks.

Steps

1. 1

   Review supported chat and voice channels

   Start by understanding how Voice Call fits into OpenClaw’s channel model. OpenClaw treats Voice Call as one of many chat channels, all connected through the Gateway, so you can reuse the same routing and agents you already use for text.

   Scan the supported channels list to confirm Voice Call is available alongside your existing platforms.

2. 2

   Understand how Voice Call connects through the Gateway

   Voice Call uses the same Gateway that powers your chat channels, so calls route into your agents through a unified entry point. This means you can run Voice Call alongside Telegram, Slack, or WhatsApp and let OpenClaw decide which agent handles which conversation.

   Keep in mind that Voice Call is a plugin installed separately, unlike many bundled chat plugins.

   OpenClaw can talk to you on any chat app you already use. Each channel connects via the Gateway. Text is supported everywhere; media and reactions vary by channel.

3. 3

   Plan your Voice Call provider integration

   Decide whether you want to connect Plivo or Twilio for telephony, since the Voice Call plugin supports both. Your provider will send call events into the OpenClaw Gateway, where they become channel messages that your agents can respond to.

   Check your provider’s console for webhook configuration so you can point it at your Gateway once the plugin is installed.

4. 4

   Run Voice Call alongside other channels

   You can enable Voice Call without disabling your existing chat channels. OpenClaw supports running multiple channels at the same time and routes messages per chat, so a phone call and a Telegram DM can hit the same agent concurrently.

   This is useful when you want a single agent brain that can talk over both voice and text.

   *   Channels can run simultaneously; configure multiple and OpenClaw will route per chat.
   *   Fastest setup is usually **Telegram** (simple bot token). WhatsApp requires QR pairing and stores more state on disk.

5. 5

   Apply channel routing and security to Voice Call

   Once Voice Call is wired in, you use the same routing and security concepts as other channels. Channel routing decides which agent handles which incoming call, and DM pairing or allowlists protect who can reach your agents.

   Reuse your existing Groups and Security configuration so Voice Call behaves consistently with your chat channels.

   *   Group behavior varies by channel; see [Groups](https://docs.openclaw.ai/channels/groups).
   *   DM pairing and allowlists are enforced for safety; see [Security](https://docs.openclaw.ai/gateway/security).
