@Sami OZCAN Thanks for reaching out to Microsoft Q&A apologize for any inconvenience caused on this.
Azure Communication Call Automation supports IVR system and DTMF gathering inputs from the input call.
For IVR system ACS utilizes the Cognitive service (like Text to speech) and below are the list of regions where Azure AI is supported to integrate with Communication service.
Refer to the below list of documentation to achieve/implement IVR system using ACS:
- About callAutomation and its supported capabilities.
- Connect to ACS with AI service (Cognitive Service) and play action on how to play an audio or text to specific user or to all participants in the call.
- Gathering user input from the call either using DTFM or using Voice recognition (speech to text) and its implementation.
You can also refer to this simple IVR solution build on ACS call automation.
As Vahid Ghafarpour mentioned in the below yes, currently DTMF enhancements is in public preview, and it is not recommended for productions scenarios. Feel free to reach back to me if you have any further questions on this.
