How-ToReceive Messages using UCMA

Hello,

I got 2 UCMA Applications:

1. One website creating a conversation.
2. One console app to receive message.

Actually, the first one working properly.
The problem is that I cannot receive message from my console app.

Which event I have to subscribe to receive message? Is it possible without the LyncClient object?

Thanks in advance ;-)

Mafyou.
