SIP Plugin doesn't appear in admin console

I just setup Openfire for the first time and it seems like everything is working fine – I’ve got Spark running on a few clients and some plugins installed and working (Content Filter, MotD, Presence Service, etc.) I am having trouble with the SIP plugin – I didn’t get any errors during the installation and it shows up on the list of installed plugins, but I can’t for the life of me find where I can configure the settings. I thought it would be under Server Settings or a new tab next to Media Services, but it’s not there. Any idea why this would be?
