Before connecting to WhatsApp, you need a phone number purchased through HighLevel. This number will receive the WhatsApp verification code during setup — either by SMS or by phone call (via call forwarding).

Call forwarding is required if your LC/Twilio number only has voice capabilities. During WhatsApp registration, Meta will send a verification OTP via phone call — you must be able to receive it.
