When the DND service was introduced by the NCC in 2016, specifically on the 1st of July, very few of us envisaged what would have resulted from this policy. While of course, it has helped in checking the incidents of spam and scam messages, for which it was intended, it has also affected a lot of businesses.
One of the industries that have been hit hard by the DND policy is the SMS or Text Messaging industry. A lot of businesses that depend largely on the delivery of time-sensitive SMS to their customers, both present and prospective, such as those who deliver OTPs have been affected negatively.
If you currently run a business that involves the delivery of OTPs (One-Time Password) to your users, particularly on your website, you might be familiar with the challenges DND poses. Several times, you might have experienced situations whereby your customers are not able to complete their transactions or authenticate their user profile because they cannot receive SMS as at when due to do this. All thanks to Do Not Disturb (DND).
Well, thankfully, in this era of DND and the frustration of undelivered SMSs, Voice OTP has come to the rescue.
How Voice OTP Provides the Needed Solution to the DND Problem
Well, as the name implies, Voice OTP refers to the delivery of OTPs via voice. That means while SMS OTPs are delivered through a text message on the user's phone, Voice OTP comes as a phone call on the phone of the user requesting for this, and it's played out as audio.
The benefits of Voice OTP as an alternative to SMS in this DND era cannot be overemphasized. One thing that stands out is that with Voice OTP, non-delivery of OTPs is not an option. Over Voice, the restrictions on delivery of SMS to some numbers due to the DND policy are not there. You can be certain that every OTP you send will get delivered to your customers. And therefore, user authentication and completing transactions have become much easier.
