Send Failed SMS OTP Via Voice Using Automated Fallback Solution

Business logins and transaction authentications are certainly dependent upon the one time password on the registered mobile number. It is not only the delivery that matters but also the time taken to receive OTP SMS. The OTP has a time limit and it expires after that time span. So the SMS OTP has to be delivered on time to fulfill the code verification functionality smoothly.

 

There may be a number of reasons for the SMS OTP delivery not arriving at their destination. Here we cover the most common issues encountered in SMS failure. 

 

  • Mobile Device or network issue.

  • Inappropriate service by OTP service provider 

 

Identifying and troubleshooting destination devices

 

If the SMS OTP sent using the API and reports show successfully delivered, you still want to check on the receiving device to make sure of OTP delivery. But the OTP is missing and has not reached its destination. You need to do the following checklist given below:

 

  • Check for the phone number submitted is correct.

  • Ensure mobile phone is switched ON or not on airplane mode at the time of OTP delivery. 

  • Mobile phone settings are updated to receive SMS respective to the carrier. 

  • Check for the network connectivity, signal strength and frequency band.

  • Is your device in the home network? If you are not in the local vicinity, Check roaming services are active? 

  • Does your device have enough space to receive new SMS? Sometimes lack of space does not allow the receiving of new SMS.

 

If you have checked all the above points are ruled out and still the SMS OTPs are delayed or not working properly. Then, the fault is on the OTP service provider’s end. You must think about the alternative switch options for better scalability and services. 

 

Check for OTP-delivery

 

If you are getting trouble in otp service, you must check it upon your numbers at least 3 to 5 times a day for three days. You must see SMS delivery issues using the same country code and collect 5 logs/day for 3 days. Look for the delivery, failed and time taken to reach. If the same problem persists again and again on collected data, it's the right time to choose an alternative SMS OTP Platform

Note: Before adopting a SMS OTP service you must use the trial plan for a week.  

 

 

Failsafe Fallback for OTP

Simply what will you do if the SMS OTP failed. The otp service provider must implement a feasible solution that delivers the message information within the time limit. Suppose the one time password for login into an application failed. What will the user do next? Users could not have a substitute option to login into the panel. This could become the hiccups for the business growth.

 

Authkey’s API is featured with fallback to overcome the situation of false delivery. It aligns the additional sending channel in standby. If the delivery time of OTP SMS exceeds, an automated voice call or the email will be triggered with the same one time password information.

Trigger OTP on phone call

The voice calls are faster to reach as compared to SMS. Engaging an automated  phone call if the SMS failed to reach is a better alternative to convey one time password. The voice otp requires an answer to a live call, the text to speech is used to speak up otp number on phone call. 

 

Trigger OTP on email

The delivery rate of an email is also on the faster side but it has a low open rate. When it comes to reading important content every user opens the inbox email frequently. The email is also a best option to receive the one time password as well as verification links on sms otp failure because users can open the login panel and email panel on the same system. It would be very easy to reach the passcode side by side. 

 

 

Analytic reports

You can check all the SMS OTP sent on the dashboard. You will get a detailed report for each OTP. Console report will give you the delivery status, failed, and latency reports. 


You can view more details about a failed attempt at troubleshooting by clicking the timestamp associated with the message.

Here's an example of what a failed message looks like:



Do the fallback need separate API integrations for SMS, Voice and Email OTP?

This is common that hits our mind because of usage of different channels simultaneously. SMS, Voice and email use different paths and routes so we require different APIs to integrate. 

No, we dont require the separate API integration belonging to different channels. Authkey.io offers you one API that is developed to communicate on all the channels simultaneously and parallely. Take a look below to understand more in detail.

 

Send SMS and Voice OTP parallely
