BTW, how do you forward your voicemail to Google Voice Voicemail? Any manual?...
update: found the instructions.
"While having a Google Voice number is handy, the fact of the matter is that on whatever phone you call a person from (landline, cell phone, etc), many people are used to calling you back at the number you called them from.
Here's a master list by cell provider of conditional forwarding codes and directions to set up your cell voicemail so that unanswered/ignored calls to your cell go to your GV voicemail, Callwave-style (for those of you who have used that service!)
Caveat: depending on your cell phone provider, it can take anywhere from 6-10 rings for your GV voicemail to pick up.
DIRECTIONS:
1. Find your activation code in the list below.
2. Enter the first code exactly as written, as if you're dialing someone. Replace [GVnumber] with your GV phone number. For example, if your GV phone number is 203-555-1212, and your service is CellCom, then you would enter *682035551212.
3. Press "Send" or "Talk" or "Enter" on your phone to dial that number.
4. If multiple codes are given, repeat steps 2 & 3 for each code. THIS IS IMPORTANT.
5. After following the steps above, try calling your mobile
phone from another phone and leave a voicemail. The message should appear in your GV inbox!
