Ever been one of those without AT&T’s visual voicemail? Think the voicemail transcribing and redirection based on rules are cool features of Google voice? Have a calling plan with a GSM based provider? Now you can forward your voicemails to Google Voice and have all those cool features. From your phone’s keypad enter the following and press the call button:

*61*123456789# (when you don’t pick up)
*62*123456789# (when you decline the call)
*67*123456789# (when you’re on another call already)

where 123456789 is your 10 digit GV number.

To cancel:

##61#
##62#
##67#

Found it here. (Dunno if the pingback worked…)
