Successfully migrated my VOIPo number to T-Mobile, then ported it to GV and have my Panasonic cordless answering system connected to my Obi 200.
All works well.
For home use, the family needs to access voice mail from the local handsets. I shortened the ring on the Panasonic so that it picks up the call before GV, and all incoming calls are answered without issue, and VM light blinks, etc.
The Panasonic allows entry of the providers VM number as well, so you can by-pass the local answer. What number do I enter to have it call Google VM instead of using the Panasonic answering machine? Google Voice forum said to enter <google voice number>PP<google voice PIN>. I have not done that yet, and have not set up a PIN in Google Voice.
Should this work? I infer from various posts that if I set it up that way, the blinking message light would not work on the Panasonic. True? If so, I am going to be forced to re-program my wife. That task may be the most formidable of all!
Set up a PIN at Google Voice. Also setup Google Voice to email and text when there is a new message. When calling yourself you will be asked for the PIN followed by the pound key and then will have access to VM. Unfortunately there is no VM indicator sent to the phone.
Understand about the spouse issue, mine is also very hard to reprogram.
Good advice. I shall continue to work on the wife.
