I’ve had a problem ever since I got the iPhone, whereby sometimes voicemail ended up at Google Voice where I wanted it, but sometimes AT&T intervened, and callers were greeted with a message that I had not set up my mailbox, which I hadn’t. I figured it had something to do with whether the phone was on the network, out of network, powered off, etc. As I have Google Voice answering for two phones potential complications were doubled.

I don’t remember if this problem extends back as far as GrandCentral days. However at some point GrandCentral/Google Voice did something about this. They added some functionality in the Voice settings which walks you through forwarding Voicemail only to Google Voice. So now it doesn’t matter whose voicemail wins the race, they all point to Google Voice. I expect this will be quite a boon for my interpersonal relationships.
