Does anybody here also notice a lag during Google voice calls?

Sometimes the lag is up to half a second or one second, and it can really make conversations difficult because you start interrupting the other person (even though you don't realize it and think you started talking when there was a lull in the conversation).

Definitely. This is the only reason I won't use GV as my primary number. I don't call often, but when I do, I expect it to work.

(However, after reading some of these comments and using my noggin, I'm not sure I'd trust something as critical as my phone to a company who's notorious for no customer service.)
