You can build an IVR system in Java by using the Azure Communication Services Call Automation SDK to handle inbound calls, play media, and recognize DTMF inputs or speech to route callers automatically. It automates server-side interactive voice response workflows without managing telephony infrastructure directly.

Call automation in Azure Communication Services allows server-side applications to control call flows programmatically. You need it when building contact center solutions requiring automated call routing, recording, interactive voice response, or AI-powered voice interactions using Java.

To make an outbound call, set up a CallAutomationClient using your endpoint and credentials, then initiate the call using CreateCallOptions. Once connected, the Java SDK allows you to trigger media playback and start speech recognition or DTMF collection during the active call flow.

Yes, the Azure Call Automation Java SDK supports server-side call recording and participant management. You can automate starting and stopping recordings for compliance, as well as add, remove, or manage participants within unified communications or contact center applications.

Yes, you can integrate both speech recognition and DTMF recognition in a Java call routing application. The Azure Communication Services Call Automation SDK processes voice inputs and keypad tones to trigger automated call routing logic and interactive voice flows.

Using Java for server-side call automation requires managing asynchronous event handling for call states and media operations. You must ensure your Java application environment maintains persistent connections to process real-time call events, speech recognition, and DTMF signals without timeout interruptions.
