Hi Ben,

Thank you very much for your inputs.

This customer wants to implement on-premise PSTN integration with CloudPBX when they currently do have on-prem Skype for Business 2015.

According to this article (https://technet.microsoft.com/en-us/library/mt455212.aspx) we can still leverage SBC for this scenario.

Please confirm. Many thanks.

That's exactly right, you can use an existing on-premises Skype for Business deployment instead of the CCE solution. The existing deployment needs to have an Edge server role deployed in order to do this.

At a very basic level; inbound calls will come in from your carrier, hit the SBC, be passed to the on-premises Skype platform, and then routed out the Edge server to Skype for Business Online. Outbound calls quite the opposite.

So in that instance you'd just need the SBC(s) on it's own without the embedded CCE components.

Kind regards
Ben
