    I am currently having some trouble when I use communicator to make a call to someone that is a contact.  Below is the errors I was able to grab from the Windows Application log.

    Then using Snooper I was able to grab the trace file from the tracing folder to get more detail.  This is what I was able to get from that:

    While testing this, I was also running a debug session on the Medation server as well to see if something was set wrong and the server never even got the invite. 

    Any thoughts?
