I have never seen the page "SP1 and SP2 Service Statistics" ever show any statistics. Neither during nor after a call, whether it be on Sp1 or Sp2 I have never seen this page show anything. Is this page reserved for future use or am I the only odd fellow here? Curious minds, you know.
Curious mind - try it with SIP based services, not GoogleVoice. Nothing of interest here, really.
