Cannot Release ACS telephone numbers through the number management portal

Try to release numbers through the Azure Communication Service system.

This message. In some countries, releasing a telephone number needs to be done through our Service Desk team. To release the telephone number in these countries, follow the steps below:

Open a new case through the link below.

Select “Azure Communication Service” as your Customer Profile.

Select the Country/region where you would like to release phone numbers.

Select Release telephone numbers as your case type, fill the rest of the case and submit.

There is no release telephone number case type, and there is no way to contact the phone number portal for this situation. General inquiry just produces a bot.
