I apologize, but based on the provided knowledge sources, there is no specific information about phone verification using WhatsApp in Ory's products. The documentation primarily discusses SMS-based verification and email verification. Ory does support phone number verification via SMS, as described in [Ory Kratos documentation](https://www.ory.sh/docs/kratos/self-service/flows/verify-email-account-activation#phone-number-verification). However, WhatsApp is not mentioned as a supported channel for verification. If you need to implement phone verification specifically through WhatsApp, you might need to explore third-party solutions or custom implementations that are not directly supported by Ory's current offerings. For phone verification using SMS in Ory, you can configure it as described in the [SMS sending documentation](https://www.ory.sh/docs/kratos/emails-sms/sending-sms). This allows you to set up SMS delivery through various providers or your own HTTP-based service. If WhatsApp verification is a critical requirement for your project, you may need to consider alternative solutions or reach out to Ory support for any potential custom integrations or future feature plans.
