Now how do I access my voicemail on the cell phone?
Call GV number, when Obi AA picks up press 2 and dial GV number, when GV voicemail answers press *, enter Pin, etc...
To make it easier: Add your GV number to a Speed-Dial in ObiTalk
Then to access voicemail from cell: Call GV number, when AA picks up press 2, Speed-Dial GV#... it should go straight to voicemail.
