cluckercreek ,
Thank you for your reply. I checked my settings and found MWIEnable and X_VMWIEnable checked(200 has 1 phone line) but AnnonymousCallBlockEnable not checked. I went ahead and checked it just because it seemed like a good idea. From what I have been able to find it seems this problem may only affect some people, myself, ceg3, and a few others. Maybe this is a problem with certain locations. I remember seeing posts about GV taking a long time to connect and poor voice quality which just may have been due to their location since most people, including me, found GV works very well.
The update to build 4420 was done automatically. When I clicked on GV from the providers list a note popped up telling me to wait while my Obi was being updated. From what I read in another post about Google Voice being back, a reply by SteveInWA , it seems that this build may be targeted just for GV service. That is just my guess.
Considering that when you were updated to build 4412 some of your settings were changed, maybe build 4420 was done to correct that problem, because when I got that update none of my settings were changed.
