Please Note: I found out through my own various systematic testing that NetComm NB9WMAXX is not compatible Internode VoIP and vice versa. I tinkered with every possible configuration available on the NetComm NB9WMAXX to no avail. I even went as far as Telnet-ing to the modem and turning off the firewall but still experienced problems. I ended up signing up with MyNetFone and all my problems disappeared!
