I have the latest IncrediblePBX installed and have it setup with an oib202 as described here: http://nerdvittles.com/?p=25846. My issue is that when I call in and no one answers the phones the voicemail that picks up is not the PBX but rather Google Voice. I have tried decreasing the ring time on the ring group to even 5 seconds but that does nothing. Where can I start digging to see what is going on with this?
