VoipNow Call Interactive

Overview

This is the Call Interactive Guide. It explains the Service interface and the responses of the Service. The Call Interactive is a web service that enables developers to interact with the system every time an IVR places, receives or terminates a phone call.

Call Interactive can be used in various scenarios. For instance, you can use it:

• To integrate with Customer Support applications
  The customer will provide a subscription ID over the phone, which will be verified by the remote logic. Based on the result, the customer may be directed to a call queue.

• To integrate with phone payment applications
  The customer will provide information on the billing format they prefer. The remote software application will process the request and answer with text-to-speech or pre-recorded files, based on the result of the call.

• To make a transfer to a specific resource based on the customer behavior
  Based on the customer walk through the IVR, a remote application can decide the steps the customer must take over the phone.
