Web-to-phone transfers are not supported in Vapi. If you attempt to transfer a web call to a phone number, the call will always fail or drop due to platform limitations. *Action*: Consider using phone-to-phone or SIP-to-phone transfers instead, as these are supported. For more details, see the [Vapi documentation on transfer limitations](https://docs.vapi.ai/phone-calling/transfer-calls/debug-forwarding-drops).
