I'm running Openfire 3.4.3 on a linux machine, and using Spark 2.5.8
I installed the Red5.war file on the server and can access the property page find. However I can't seem to use it with the client. I copied red5-plugin.jar into the Spark plugin directory, and when I right-click on a contact and select Call, the contact will see a small popup saying "Incoming Call". Thats where it ends. It goes away after a few secs, or if I click on it it also goes away.
Both clients have the plugin. I've tried calling on both clients and still nothing.
One odd thing, when I click Spark >> Plugins, Red5 doesn't show up.
