I am building a technical proof of concept using Azure Communication Services Call Automation and Deepgram Voice Agent API. I need one Spanish local/geographic phone number for controlled inbound test calls. Azure Portal shows that Spanish local numbers are only available through special orders. However, the special-order window does not provide a Number Request Form for Spain. It only provides forms for the United States/Canada/United Kingdom/Denmark, Ireland, Italy and Sweden. Please confirm the correct acquisition process and help provision the following number: Country: Spain Number type: Local / Geographic Preferred area code: Madrid 91 Quantity: 1 Use case: Application / A2P Calling capabilities: Inbound and outbound voice SMS capabilities: None

    For Spain, Local phone numbers are available with Make Calls: General Availability and Receive Calls: General Availability. SMS send/receive is not available for Spanish local numbers.

    To acquire a Spain phone number:

    1. Use a paid Azure subscription. Phone numbers can’t be acquired with Azure free credits.
    2. Verify the subscription billing location is one of the supported countries/regions for Spain phone numbers: Australia, Canada, France, Germany, Italy, Japan, Netherlands, Spain, Switzerland, United Kingdom, United States.
    3. In Azure portal, open the Communication Services resource.
    4. Go to Phone numbers in the left menu.
    5. Select Get to launch the purchase wizard.
    6. Choose Spain as the Country/region.
    7. Choose Local as the number type.

    If the portal requires special ordering, the documented process is:

    1. In Phone Numbers, select Request a Special Order.
    2. Open a new case at https://aka.ms/ContactTNS.
    3. Select Azure Communication Service as the customer profile.
    4. Choose the required Country/Region.
    5. Select New TN Acquisition as the case type.
    6. Fill in the request details and submit.

    The available documentation confirms Spain local number availability and the general/special-order acquisition flow, but it does not provide a Spain-specific number request form list or a direct provisioning path for a Madrid 91 number from here. The supported next step is to submit a special order case for Spain / Local / 1 number / inbound and outbound voice / no SMS through the documented special-order process.
