Aws Connect on-call support for Cambodian number

I apologize, but there seems to be an issue with making calls to Cambodian numbers using Amazon Connect for your on-call support. This could be due to several reasons:

1. Country Code Restrictions: By default, not all countries are allowed for outbound calling in Amazon Connect. You may need to request specific permission to call Cambodia.

2. Regional Limitations: The ability to make outbound calls to certain countries can depend on the region where your Amazon Connect instance is located. Some regions may have restrictions on calling specific countries due to regulatory reasons.

3. Telephony Settings: Ensure that outbound calling is enabled in your Amazon Connect instance's telephony settings.

4. Queue Configuration: Check if the outbound caller ID number is properly configured for the queue you're using for these calls.

5. User Permissions: Verify that the user or agent attempting to make the call has the necessary permissions, including "CCP: Outbound" permission.

To resolve this issue, you should:

1. Verify that Cambodia is on the allowed list for outbound calls in your Amazon Connect instance.
2. Double-check your telephony settings, queue configurations, and user permissions.
3. If the problem persists, you may need to open a support case with AWS. When doing so, provide details such as your Connect instance ID, the phone numbers you're trying to call, and any error messages you're receiving.

AWS Support can help you determine if there are any specific restrictions or requirements for calling Cambodian numbers from your Amazon Connect instance and assist in resolving the issue.
