11/12/2025, 7:47 PMcall.in-progress.error-vapifault-azure-voice-failed might indicate a failure with Azure's voice services. For resolving these issues:
1. Azure Speech Transcriber Support: Ensure you have correctly specified AzureSpeechTranscriber as an option for your transcriber to utilize Azure's speech-to-text capabilities. More details can be found in the [changelog](https://docs.vapi.ai/changelog/2024/12/13).
2. Call Ended Reasons: Confirm the cause of any call disconnects or errors, check the endedReason code in your call logs for further insights on failures [here](https://docs.vapi.ai/calls/call-ended-reason).
Please verify these configurations and let me know if you need further assistance.
