Besides provisioning a new phone number, you can enable voice calls on your own WhatsApp number. Your customers call from the same chat where they already message you, without dialing a different number. It’s configured on the WhatsApp channel screen, not in Voice.
Available for WhatsApp Cloud API and Gupshup numbers.

​
Enabling calls

The WhatsApp calling section lets your customers call that number by voice on WhatsApp, and has two nested toggles.
1

Receive WhatsApp calls

When enabled, your customers can start a voice call with this number from their WhatsApp chat. It’s the main toggle: without it, nothing else applies.
2

Show the call button

Displays the call icon in the chat and on the business profile. Turn it off if you want to receive calls without showing the button.
Turning off the button while leaving calling enabled is useful for a gradual rollout: you can test with a group that already knows the path, or keep the capability available without inviting all your traffic to use it from day one.

​
Connecting a voice agent

The ElevenLabs voice section creates an ElevenLabs voice number (SIP trunk) for this WhatsApp number and assigns a voice agent to it.
This section stays locked until you enable Receive WhatsApp calls. The panel says so itself: first you enable calling, then you connect the agent.
Once calling is enabled, you pick the voice agent from the dropdown and confirm with Connect.
The agent you connect here is one of those you already created in Voice. If you don’t have one yet, create it first: see Voice agents.

​
How it compares to a provisioned number

Both paths end in the same place — a voice agent answering calls — but they don’t serve the same purpose.
They’re not mutually exclusive. It’s common to have WhatsApp calling for inbound support of existing customers and a separate provisioned number for outbound campaigns.

​
After connecting

Calls that come in through WhatsApp are logged like any other, with their recording and transcript.
