Glad to hear this got fixed. So for future reference, seems like it takes Google Voice about two weeks to deal with an issue like this (was the same when Google Voice was suddenly unable to send calls to certain Gizmo5 accounts last year; it took them a little over two weeks to fix that as well).
I guess this is acceptable for a free service, but heaven help them if they ever start charging for Google Voice service and it takes them this long to fix something like this, because I suspect that paying users would not have much of a sense of humor about this sort of delay.
But for free, I guess we have to learn to live with hiccups like this.
