Caller identification
The system had to recognise registered phone numbers on dial-in and fall back to a PIN for everyone else.
Next Generation Communication: Call shop platform with online payments
Prepaid calling, fully self-service.
We built Callingo for Next Generation Communication: a call shop platform that connects callers through access numbers, manages prepaid accounts and payments, and routes each call over the cheapest route.
The Challenge
What stood in the way.
A prepaid calling service has to identify callers as they dial in, keep balances topped up and connect calls at a competitive cost. It also has to take payments from several sources.
Account top-ups
Customers needed to recharge by PayPal, credit card or voucher, and some wanted balances recharged automatically.
Payment integration
The platform had to work with popular credit and account processing merchants, including PayPal and First Data.
Call cost
Each call needed to be routed over the cheapest available route.
Our Solution
How we answered it.
We built Callingo as an ecommerce calling application with three modules: a client module, an admin module and the calling service. Together they handle registration, dial-in validation, payments, history and call routing.
- ProblemCallers had to be identified on dial-in, whether or not they had registered their phone.Our answerThe system checks the calling number against registered accounts and asks for a PIN when there is no match.
- ProblemPrepaid balances could run out mid-use.Our answerA scheduled Windows service checks accounts that have opted into auto-recharge and tops up low balances from the customer's credit card.
- ProblemCustomers wanted to pay in different ways.Our answerWe integrated PayPal and First Data gateways alongside voucher redemption, and connected Callingo to popular credit and account processing merchants.
- ProblemEvery call had to be connected at the lowest cost.Our answerWe integrated Callingo with hardware switches so calls are routed over the cheapest route.
How It Works
The parts that made the difference.
Dial-in validation
When a user dials an access number, the system validates their phone number or asks for a PIN, then connects the call to the number they want.
Accounts and speed dial
Users register a phone number to their account, or are given a PIN, and can add numbers to speed dial.
Online recharge
Users recharge their account with PayPal, credit card or a valid voucher number, through integrated PayPal and First Data gateways.
Auto-recharge service
A Windows service runs at set intervals, finds accounts with auto-recharge enabled and a low balance, and recharges them from the customer's credit card.
