Desktop IE 8.0 (on my desktop PC!) says canInitiateVoiceCall=True
My IE 8.0 (user agent string : "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0)" ) says it canInitiateVoiceCall - this is wrong, it can not.
This is a Windows7 PC.
