Adding userendpoint to Application endpoint's Default routing UCMA 3.0

Hallo,

I have established an Application endpoint with the following properties

               settings.IsDefaultRoutingEndpoint = true;
                settings.AutomaticPresencePublicationEnabled = true;
                settings.Presence.PresentityType = "automaton";
                settings.Presence.Description = "AlwaysOnlineBot";

then established an userendpoint with userendpointsetting having the following properties

   userEndpointSettings.AutomaticPresencePublicationEnabled = true;
    userEndpointSettings.Presence.PreferredServiceCapabilities.AudioSupport = CapabilitySupport.UnSupported;

If i start the application for the first  time and a call arrives for established user endpoint it is not received by the application endpoint. Starting the app for the second time the application endpoint receives the calls for the user endpoint.

So the default routing works for the user endpoint that were established  at the time of establishment of the Application endpoint. It doesn't work for user endpoints that were established after  Establishing Application endpoint.

Is there a way of adding newly established user endpoints to application endpoint's Default Routing?

Thanks in advance

cheers
