Azure Communication Service - Traffic Flow

Question

Azure Communication Service - Traffic Flow

Micallef, Mark 21

Hi,

A couple of quick questions regarding Azure Communications Service traffic flow. I've looked around and haven't had any luck in finding answers. Any help would be greatly appreciated.

1) Does traffic between ACS and integrated Azure services (ex. Teams) traverse the public internet?
2) Does traffic between ACS and a Trusted Service located in Azure traverse the public internet?

If so, is there any way to configure ACS to prevent traversal of the public internet?

Thanks in advance.

@Micallef, Mark Thanks for the patience on this.

1) Does traffic between ACS and integrated Azure services (ex. Teams) traverse the public internet?

"ACS and Teams users joining Teams meeting via ACS SDKs are using public internet to access ACS and Teams services. Teams users joining Teams meeting via Teams client are using public internet to access Teams services. The traffic is not traversing public internet between ACS and Teams services.

2) Does traffic between ACS and a Trusted Service located in Azure traverse the public internet? -->Could you describe more details about your requirement/use-case.
Hope from above/#1, it clarifies now.

Thanks so much for the information. Very helpful!

As for question 2. Based on the response to question 1, I believe I know the answer. But just to clarify...

Assuming the architecture below, does the Trusted Service traffic (to or from ACS) traverse the internet?

@Micallef, Mark , Yes it does. Contoso Trusted service is service of developer that communicates to public endpoints of ACS.
