One Time Password ( OTP ) that works *Without SMS

Postby matemesh » Sat Sep 26, 2015 9:04 am

Hello All,

I am new to asterisk and I am not a asterisk developer or expert, I am looking for an expert who can help or develop a solution for me

I am looking for an innovative approach for customer phone verification. It replaces SMS based one time password, with an OTP over a missed call ( to mobile, landline phone ) Thereby eliminating any Cost, Delay & Dnd Hurdles.

1. Customer submits a form with phone number on
2. Asterisk will make a miss call to Customer's Phone with CID like 123456+3 digit code (this 3 digit code will change every time)
3. Customer enters the number from which he/she received the miss call
4. validates number with server
5. Number matched, Verification Successful !

Someone already created it and using it.
I need someone who can help me with Asterisk part

The demo is available at ( Enter your number with country code and without + Sign, then you will receive a miss call from a number like 123456 + 3 digit code, Enter the number without + sign)

If any can help or create this solution please contact me at

If I were a network operator and discovered my customer was doing this, I would invoke the fair usage clause in their contract and either deny service, or renegotiate the contract to charge them for say a 30 second call, even when the call wasn't answered.

That's even assuming that they allow through anything other than the exact CLIDs that they have verified for the customer, and that the maximum number length won't be exceeded somewhere in the network (e.g. for international calls).
