We are running Wildfire 2.5.0 and Windows Spark v1.1.1 clients. Wildfire is running on a CentOS box with nothing else on it connecting to our Asterisk 1.0 box. We have our Asterisk plug-ing configured correctly and call generation, call screen pop-up notification, and all chat functionality works fine. However, today a user transfered a call to another user and now her IM status is stuck at "On the phone". I have tried everything short of stopping and starting Wildfire. Anyboby have any ideas or suggestions?
