Over the years, OTPs have proven to be very effective in acting as an important extra layer of security when carrying out online transactions, especially the ones that require your user data and other sensitive information. With this OTP provision, your users or customers can authenticate their transactions which helps to protect them from fraud and other criminal activities.
We have already prepared a blog article discussing in detail what OTP is and why it is beneficial. See it here.
When it comes to using OTPs, you have the option of SMS OTP which has been for a long time and is still the popularly accepted form of OTP delivery. This option works in a way that the OTP is sent to the phone of the user or customer via text message. However, there is another option for delivering OTPs which is the Voice OTP. Let us now see some reasons why you should choose Voice OTP for your One-Time Password.
One of the advantages that Voice OTP offers over other OTP delivery options is the promptness of delivery. Businesses who use SMS OTP have often experienced delivery delays, all thanks to some network-related issues on the part of the providers such as traffic, service outage, or gateway timeout. Because of this, users needing OTP to authenticate transactions might not receive it on time, and based on the time-sensitivity of this, it frustrates such customers. With Voice OTP however, this issue is well taken care of.
Additionally, there are cases of certain phone numbers not being able to receive SMS at all. One of the major causes of this is the Do-Not-Disturb (DND) policy that has lasted for a long time now. Phone numbers active on this service find it difficult to receive SMS. Voice OTP on the other hand is not affected by such policies and limitations.
It is worth noting that when SMS is sent, which is also applicable to SMS OTP, you are often at the point of sending the message. So, then, what happens when the message does not get delivered? Your guess is as good as ours, you’ve been charged for a service you would feel you didn’t get value for. The good thing about Voice OTP is that you are only billed at the point when the customer or user picks the call on his number and listens to the password being read out. Thus, you are sure that you are paying for a service that you’ve enjoyed.
In fact, a lot of business owners who already have SMS OTP integrated into their system also have Voice OTP added as an alternative when SMS OTP fails. Whichever one you decide on, there is no denying the fact that Voice OTP is a necessity for your business when it comes to delivering One-Time Password.
