POTS trunk (OBi110 device) returns "Answered" ruining a ringall strategy --FreePBX. I am trying to ring some local IP phones and 3 trunks in a ringall stratedgy. But as soon as a call goes out on the OBi110 it reports "answered" and the call gets connected. It isn't really "answered". The ringall stops. This happens even though I have specified "Confirm Calls" in the ring group.
