What is a calling card solution?

A calling card solution lets callers dial a local access number, enter a PIN and reach international destinations at VoIP rates. No app or special phone is needed on either end.

We build the platform that runs this business: card generation, authentication, voice prompts, routing and prepaid billing. You manage cards, rates and resellers from a web panel.

Built for

  • VoIP service providers

How it works

From access number to connected call

A caller dials your access number. The platform checks the PIN or caller ID, reads the balance and plays the prompts. It then routes the call over your chosen carrier and deducts the cost in real time.

  • Hosted in the cloud or on your own servers
  • White-label web portal for you and your resellers
