I have a Google voice number which forwards to my iPhone's number. I'm wondering if there's any way to make AT&T handle the voicemail rather than Google Voice. This way I will be able to use the Phone app to view voicemails rather than having to open a browser with Google Voice.
I understand that if I use it this way I won't get transcribed voicemail. That's fine, that's not the reason I'm using Google Voice.
Ideally I want Google Voice to handle voicemail when my phone is off or in airplane mode, and when my phone is on and I have a signal, I want it to use my phone's answering machine. This way I get notified of voicemail via WiFi when airplane mode is on, but when my cell signal is on, I get to use the nicer interface of the Phone app.
