I use a google number for a business that is forwarded to my cell using Google Voice. I have switched from Sprint to ATT and am no longer able to use the custom voicemail messages for individual callers. Looking at the Settings page of Google Voice in "Calls" it shows the Sprint logo, and I haven't found a way to switch carriers to ATT. I assume it should show ATT?
What I am looking for is this - I do not care if I have to use Google Voice or the stock voicemail app.
1) Any call coming into the phone using the Google Number hears a business message
2) Any call coming into the phone using my cell number hears a personal message
At a minimum:
1) Any call coming into the phone that is not set up as a contact hears a business message
2) Any call coming into the phone that is a contact hears a personal message
