Ideally, you'd want your service client to be able to make outbound calls and also host inbound ones. This sort of solution where both the client and service can send messages to each other independently is called a duplex service. In this fashion, our client could makes an asynchronous call, and the service could delivers an out-of-band response event that the client would handle, accordingly. However, this approach is neither interoperable nor accommodating to clients and services that are online at different times.
