I am very interested in creating a CallManager plugin with JTAPI. My first step would be to tie "presence" in Jabber to your state on the phone. This way, people who have you on your buddy list, can see if you are on the phone. This is a feature that is sorely missed in CallManager 4, and would be a great addition to my Spark install.
Has anyone made any progress connecting wildfire to callmanager?
