Question Box callboxes use GSM mobile signal for calls, and run on any local power source (solar panels, battery or mains). Using Closed User Groups (CUGs), calls are free between the callboxes and the destination phone number, greatly reducing the cost of implementation. Calls can go to either a central location, or to distributed program staff and outreach workers.

How It Works:

  • Question Box network functions as a scalable hub-and-spoke system
  • Communities set up and communicating in less than a day
  • Question Box units have speed dial buttons, and can call any programmed destination phone numbers
  • Question Boxes serve as access point between your services and the community even if no local representative is present in the community
  •  Requires sunshine for solar power, battery, and GSM signal

Question Box units can be customized to suit deployment requirements. Versions are available as a speakerphone or using a privacy handset. In places with transmission of disease concerns, a hands-free version can be custom-ordered.

Question Box callbox network integrates well with programs irrespective of whether there is an existing ICT component. Our team is also well versed in complementary ICT approaches, such as SMS, IVR, VOIP, Data for Development, and Cloud Applications. For longer or scaled implementation, our team can provide consultation to design and scale your program, as well as assist with: M&E, Training, Technical Hub Set-up, Other ICT Tools Integration and Data Analysis.
