No RonR, my Land line goes to the LINE port (OBI device) and my house phone system is connected to the PHONE port (OBI device), when I receive an incoming call from the land line the OBI is supposed to just bridge it over the PHONE port, but for some reason sometime the CNAME is not forwarded but the CID is always forwarded, it propably has to do with a delay that the OBI takes to pass the call to the PHONE port.
