Well, it is perhaps worth noting that if you fake your user agent to remove the block, calls still don't work (I've tried). I'm not opposed to blocking a feature which the developer knows is not going to work (although it would be nice if their was an override, for browser developers if no one else).
But, yes, the fact the calls don't work in the first place is BS. And it is, sadly, one of the reasons I finally gave up and switched to Chrome earlier this week. I need this stuff for work, and I just can't fight it anymore!
