QuoteFor reference I also tried to dial *67 to block PhonePower outbound caller ID and it still plays the rejected message (Darn Google Machine - they *know* everything). Interesting, the call shows up in my GV call log as an unknown caller - not in the spam folder like I thought it would.
If you block your CID you should be able to access your VM.
I think the following is what you have to do:
Call your GV number.
Wait for the VM message.
Immediately dial *
You will get a prompt something like:
"This number is not associated with your GV account. Please enter a GV forwarding number followed by a #"
Do what the nice lady asked for and you will get into your VM.
You can automatically send PP an *67 when you dial your GV number.
Add the following to the beginning of the OBI
Physical interfaces -> Phone Port -> OutboundCallRoute: {(<*67>1gggggggggg):sp1},
gggggggggg is your GV number.
This assumes PP is defined on SP1.
