yes I have got to where I can hear either by the app in Cell phone or thru the extremal port from BI install. but now I have no way to talk from BI app on Iphone, the Iphone icon is greyed and nothing happens when I push on it or hold it down. The external one that put me right in with the BI program does no even have a place to talk back thru the camera selected. Need for interfacing while travel and delivery people at the door. I have a BI app Ver 5 and a New Iphone BI app just installed. Android user for yrs, went to Iphone to interface with family more and been crazy for me since.
