I have a CM5 lab and today I installed the TSP plugin to enable Call Contacts in Outlook. When I rebooted my Dell PC running WIN XP SP2 Communicator no longer worked. I get a pop-up complaining about missing audio. I uninstalled the TSP and now IP Communicator works again. My Plantronics DSP headset was working the entire time that IP Comm was telling me it was unplugged. It wasn't. Thoughts?
