Least Cost Routing

Least Cost Routing (LCR) is an application that enables telephone calls to be ‘held’ by the telephone switch while the application performs the following: 

  • Collects and validates the call information
  • Translates the number into a new destination number (number portability)
  • Determines the least-cost route for the call
  • Transfers this information back to the switch
  • The switch can connect calls to the least cost networks and routes.

LCR can collect any forms of data, such as credit information on customers using mobiles to download games, checking customer credit worthiness, the amount of remaining pre-paid time, send message to mobiles informing users pre-paid time remaining for example. 

The data is processed and a response provided back to the data source, for example a telephone switch within 2 milliseconds.
