Help with Obi110 setup for 3CX and Google Voice

[KJ4320]

I followed the guide here http://www.obitalk.com/forum/index.php?topic=3665.0 to setup GV on my 3cx with Obi110.

I am having an issue on inbound calling. I can call the GV # from my cell phone and my handset connected to Obi rings as well as my SIP 3cx phone, but when I answer the call on either one I get silence on the line and I can still hear the phone ringing in my cell phone speaker.

It has to have something to do with off hook indication, but I am not sure where to look. 

thanks for any help anyone can offer.
