This is my first post, so I hope I'm doing this right. I read through all the posts and did not come across a working solution for the MS voice command problem on the Verizon XV6900. I just bought one, and have been trying to get it (MSVC) working the way it's supposed to. Here is what I have found. I installed the newest version I could find (1.6.19209) and almost nothing worked right, even with the fixes posted. I then tried the older ver. 1.6 and uninstalled all fixes (from here). I noticed that it will answer through my BT earpiece (both a blueant micro and the stock Motorola BT that came with the phone), but dings like there is no response after EVERY time it requests an answer. (ie when you say "call home" it will come back and ask "call home?" and it won't take your "yes") This, I found, happens on ANY response it needs, like "help", it asks "what help do you need...phone...calendar..etc... it will ding out and not hear your answer. If you un-check the "confirm when calling....." buttons in the VC-Phone settings when you say "Call home" or whomever, it will dial right out over the BT earpiece with no problems.
Well, I hope I explained it correctly, and I hope, maybe, that someone thats good at finding fixes for these things can use the observation.
