I had to get my iPhone exchanged at the genius bar. Prior voicemail would go right to google voice and I would receive voicemail by email. Now voicemail is going to iPhone. What are the settings in google voice to receive voicemail via email?
Try the "Alert me when I have new voicemails: Email the message to: [Your e-mail]" setting, accessible from the Google Voice Settings web interface / Voicemail & Text tab.
Are people even dialing your Google Voice number?
Prior to my new device people would dial my AT&T number and voicemail's would not go to AT&T voicemail, they would go to gv voicemail and I would email.
I've never heard of anything like that being possible with Google Voice, but maybe you had a special setup. I have no idea how to get Google Voice to save voicemail left on an AT&T number, unless you had some kind of forwarding to your Google Voice number set up through AT&T.
for almost two years now
op, you might need to activate google voicemail on your phone again. you can do so in the voice settings page under the phones tab.
