What is a voice authorization?
Voice authorization to the website is the equivalent of a decline. To get an authorization you must call your credit card company to get an authorization code, then input that code into your payment gateway. The exact procedure is a little different for each merchant account and gateway. You should review your gateway documentation, or contact your payment gateway provider and tell them you’re getting a “voice authorization” to learn the exact procedure. You could also safely, treat the card as a failure.
