FOR Authentication Purpose#
- Smart use of IVR based Missed Call : Phone verification
1. When a person enters a phone number in any online registration form, he is given a phone number to dial from the phone number she entered in the form within a given time say next 20 mins. The pop up clearly mentions that as soon the phone rings, it will be disconnected just after capturing the Called ID and the call will not be charged!
2. The person calls the number. The IVR receiving the call will capture the Caller ID and match it with the number entered in the online form. If it matches, the phone number will be verified and the registration would be accepted.
3. The IVR can now make an outbound call to inform that the registration is accepted and now he can proceed with his registration or any other purpose of the online form submission.
Any PRI connection in India is normally given 100 numbers in continuity. So, these 100 numbers could be used in random to get missed calls from different users in order to increase secrecy as well as security. So, missed call with an intelligent IVR system could be used as completely automated phone number verification service.
