Unable to use D365 to make international call via Teams

Hi, D365 user from Hong Kong. When making international call on Teams, we can dial in pattern of:

International Access Code (local IDD service provider) + Country code + Area code + local phone number

However, when making international call on D365 via Teams, there is no option to dial International Access Code, only can dial the contact number shown on contact details.

Any solution? 

1. Contact details (France)

2. Below pop-up

3. no option to add international access code

4. Fail to call
