## title: WhatsApp

WhatsApp can be used as an inbound Voice AI channel when your WhatsApp Business setup is connected to Voximplant.

## Setup flow

1. Connect your WhatsApp Business account and number in Voximplant.
2. Attach the WhatsApp number to your application.
3. Create a routing rule that maps inbound WhatsApp destination to your Voice AI scenario.
4. Test with a real WhatsApp call to confirm routing and media.

## Voice AI notes

* Use the same inbound connector pattern as PSTN: answer call, create client, bridge audio.
* Keep responses short and explicit for mobile-call UX.
* If one scenario handles multiple channels, branch by destination and/or metadata.

## Channel constraints

* WhatsApp calling has channel-specific account requirements and country availability.
* Validate policy and eligibility before production rollout.
