How can I manage the verification code with a customer if the phone number is tied up with an IVR?
Many businesses want to use phone numbers their customers already know such as their 1-800 or other toll-free numbers. These types of numbers are usually behind an Interactive Voice Response (IVR) system, which a WhatsApp registration call cannot navigate. Instead, tyntec & WhatsApp are able to share with you 1 to 2 two sender IDs that the registration phone call will come from.
tyntec will provide you with two sender IDs upon request. You can use this information to create a whitelist for those numbers — so that once the call comes in, you can redirect it to an employee or mailbox where the registration code will be captured.
