We want to customize our A2Billing per followings:
All card will be printed bases on PIN/Customer ID, and top up via SMS and IVR needed to be implemented per following instruction
via SMS
1. SMS your PIN to 013xxxxxx for registration/top up of your phone
2. If your PIN is correct you will receive an SMS with your new balance
Via IVR
1) Dial 1800 xxxxxx and then press *
2) Dial your PIN to top-up
Also as we have already only instruction for our customers, it should be also compatible with it(attached is the old instruction)
So following are three main things needed in this project:
1) Top up by SMS by using PIN (it should be possible for old and new customers) and confirm information to user by SMS after any top up
2) Top up by pressing * or *33# in IVR as discussed before
3) Provide me details about installing this scrip so I can do future debugging myself
