This section covers topics related to:







  • Managing IVR Projects, where you can create and design an IVR flow on the drag and drop HTML5 design area
  • ODBC, where you can set different Database connections to be used on the IVR structure
  • Recordings, where you can preview or download audio files recorded in an IVR project 




The following are the main benefits of designing an IVR Scripts:

  • offer a self-service to allow your customers to solve their issues on their own without speaking with an agent.
  • allow you to record customized greetings and messages so that when your customers call your company, 
  • Prioritize calls based on caller's value. When a customer calls, type of the caller can be extracted from a database and IVR can route VIP customers to the agent who is most qualified to meet their needs. 
  • connect to a remote DB (ODBC) to extract information

  • define the Variables and Intervals

  • use ASR to gather input and responses through spoken words 

  • perform call recording

In a typical scenario of a company that uses an IVR, the callers are first greeted and asked to choose from a series of prompts (e.g. “Press 1 for Sales”). Based on the button they pressed, the callers are routed to the most appropriate queue. If all agents are busy, the caller will wait in a queue or managed differently.
