I recently upgraded to an OBi200. It's connected to my Google Voice number. It is set up so that incoming calls ring both the cordless phone plugged into the OBi and my cell phone. I just noticed that if I answer the call on my cell phone, the landline phone keeps ringing. (Similarly, if answer the call on my cordless phone, then my cell phone keeps ringing). I never had this issue with my OBi110.
Does anyone know how to fix this so that answering a call on one phone stops the ringing on the other phones? Thanks.
