I solved both problems (warning and user status) by replacing a file /opt/openfire/plugins/astrisk-im/lib/asterisk-java-0.3.jar with asterisk-java-1.0.0.M3.jar (you can find it here: http://blogs.reucon.com/asterisk-java/).
I have same problem
while program in runnig mode it shows 'Unsupported protocol version 'Asterisk Call Manager/1.3'. Use at your own risk' . I tried solution you proposed but didn't workout. I think my Asterisk manager version is 1.3 .So can you guess which asterisk-java.jar is suitable for my task
