Win?? Lol.. You can't win with a loser. The patents are proven worthless for 8 yrs, by hundreds if not thousands of voip service provider companies plus just big investors. They all know....... There is not so far a shred of real evidence that the patents are needed, effective or of any value. All the extention applications to operate and control voip usage, have been available for many years and in multiple ways. Some is for sale and some is open source software. Everything for switching, routing, billing, etc, it's all been there for a long time. I've posted some of here before. These things are not brought up in prior art searches because it's not IN THE BEST INTEREST of those who have said there is no prior art. Vplm has been beddy beddy good to "the cabal". And the generous "contributors" to the cause, the emu go fund me, keep it going & going & going & going....
