ACS CNAM registration

Question

ACS CNAM registration

AI MSI 20

Hello,

I have submitted CNAM registration requests for Azure Communication Services (ACS) via email on July 07, July 12, and July 14, but I have not received any response or confirmation. These requests included the required details (company name, subscription ID, tenant ID, ACS resource name, phone numbers, and desired CNAM).

Could you please confirm whether these CNAM registration emails were received and advise on the next steps?

Thank you,

Hello @Aditya N . Thank you for acknowledging my post. I just want to clarify that the CNAM registration emails I submitted on July 07, 12, and 14 were sent from a different sender account than the one I used here on Microsoft Q&A. Could you please confirm if those emails were received under that sender account, and advise on the next steps for processing the CNAM registration?

Hello @AI MSI

This thread is tracked and progressed based on sub id. Is it possible for you to raise query from the sub id from which you submitted the requests.

Hello @Aditya N , thank you for clarifying. The CNAM registration requests I submitted did include the correct subscription ID. The only difference is that the sender email account used for submission is different from the one I’m using here on Q&A. Could you please confirm that the ACS team can still track the requests based on the subscription ID provided?

Hello @AI MSI

As mentioned all the process is tracked with sub id. So for troubleshooting, you may need to fill the form again that will tracked on current sub id so all logs will be different. The appropriate way could be to post query from the right sub id. Is there any issue for raising query from the right sub id?

hi AI MSI & thx for sharing urs issue here at Q&A portal,

If u've already submitted the required information three times and haven't received even an acknowledgment, there's unfortunately no way for anyone on the Q&A forum to confirm whether those emails were received.

If this is blocking your deployment, I'd also open an Azure support request so the ACS team can investigate through the official support channel. Only they can check the backend status of CNAM registration requests or determine whether any additional information is needed.

rgds,

Alex

If my answer was helpful pls mark it and additional thx if u follow me at Q&A portal

Thanks, Alex. Since I haven’t received any acknowledgment from the CNAM registration emails, could you please help escalate this by opening a support request with the ACS team on my behalf, or confirm the exact support channel that can look into my CNAM registration issue? I want to ensure the request reaches the right team who can check backend status and advise on next steps.

Additionally, how long it will take for the support request to open
