Thank you for reaching out. I understand that you are facing an issue while confirming your phone number during signup for Azure AI Speech service.
Here are some other tips:
- You can use any phone number for verification as long as it meets the requirements. The phone number that you enter for verification isn't stored as a contact number for the account.
- A Voice-over-IP (VoiP) phone number can't be used for the phone verification process.
- Check that your phone can receive calls or SMS messages from a United States-based telephone number.
- A Voice-over-IP (VoiP) phone number can't be used for the phone verification process.
- Double-check the phone number that you enter, including the country code that you select in the drop-down menu.
- If your phone doesn't receive text messages (SMS), try the Call me option.
Hope this helps. Thank you!
