Option To Receive OTP Via Call
There are cases occasionally, when customers are not able to receive the OTP via SMS. Though we use one SMS provider as described by the operator and one SMS provider from platform side as a fail safe, yet there are unfortunate circumstances when the customer is not able to receive the OTP.
Under these conditions we have added the option to receive OTP using phone call via Twilio.
Note: For Twilio, operators often need to do whitelist their country from Twilio dashboard.
