1.Business Opportunity
   Traditionally the telecom sector has been one of the most lucrative market segments in both emerging and developed economies. But also traditionally, that sector has been protected by heavy local regulation. Nowadays, however, many countries have either started or are considering deregulation of their telecom sectors. Such strong trend towards liberalization of the sector, coupled with the emergence of new technologies for cost effective transport of voice data, and namely Voice-over-IP, opens up new revenue generating opportunities for entrepreneurs all over the world.
   The calling cards business model offers a relatively low cost entry into the lucrative telecom market segment. The essence of the calling cards business model is to creatively segment customers by various demographic and/or behavioral characteristics and to design calling cards offerings to meet their specific calling needs. The calling cards business typically attracts entrepreneurs who want to enter the VoIP market, businesses with established retail distribution channels, and service providers who want to diversify their revenue streams.

3.How does the solution work?
3.1.User experience
  The user purchases a calling card from a retail or online store. 
  The user dials the local or toll-free access number printed on the card. 
  The user hears a voice prompt, asking him to enter his PIN number. 
  The user enters the PIN number printed on the calling card using the phone dial pad. 
  He hears his account balance and is invited to make a call. 
  The user dials the number and gets connected.
4.Service provider experience
  When the user picks up the phone and dials a destination number, Voip Gateway sends
  an authorization request to billing system. 
  The billing system or billing device verifies whether a call can be placed from that
  particular booth and authorizes the call. 
  VoIP Gateway passes the destination number to Softswitch and requests routing
  information.
  Softswitch returns to VoIP Gateway the IP address of the remote trunk gateway and VoIP
  Gateway connects to it. The remote
  gateway terminates the call to the destination party.
  Upon call completion, billing system or billing device records complete CDR information
  for the call and makes it available to the
  operator for billing, reporting and monitoring purposes.
