Hi,I've upgraded to the latest trunk version, and still got this failure. Finally, I sort it out. The 1.2.0 version allows the Route Header without Lr parameter, but the latest version does not. If there(in the latest trunk) is no Lr parameter in the Route Header, the username column in 'presentity' table will be null, while the PUBLISH message is not different from the one in 1.2.0 version.Regards,Kevin _________________________________________________________________ 中国十大热门旅游景点 http://search.msn.com/results.aspx?q=%E4%B8%AD%E5%9B%BD%E5%8D%81%E5%A4%A7%E…
