Try out Openfire with the Asterisk plugins installed on your Asterisk server.

You can install the Spark client on a windoze box, that connects to Openfire on your asterisk server.

spark provides an open source like replacement for something like Messenger or Communicator.

You get popup windows for inbound calls etc, and can either chat, or call from the spark window.
