googletalkplugin issues

I started having problems with google talk, specifically the googletalkplugin that I get when clicking on "phone" in gmail. I believe I have had these before. Not sure of old workarounds have all been tried, none so far work. Started off with not being able to hear gtalk dial. Then got messages like "XXX-XXX-XXXX (a phone number) cannot be reached." Uninstalled/reinstalled. Witho rebooting. Running as Asministrator. No joy. Just noticed many googletalkplugin processes running. This is what tickled my memory. A new one starts every time I start Chrome. Doesn't always go away.
