UCMA 4.0 User Available To Take A Call ?

Hi All,

I need to be able to determine if a Lync user is available to receive a call via a UCMA 4.0 application. The UCMA 4.0 SDK SubscribePresence example app works fine in that it picks up a given Lync user's presence state changes but the presence state itself seems to be de-coupled from that user's actual ability to receive a call - the user goes into "In a call" when a call starts but they can then manually set themselves back to "Available" during the call.

I believe you can determine a local user's availability to take a call via the Client SDK by iterating over the Conversations collection but I need to be able to determine this for a user I'm subscribing to in a remote UCMA 4.0 app running on a trusted application server.

Any suggestions etc.. would be very welcome.

Thanks very much

Ed James
