Hi,
Does anyone have any experience with VoIP configs for a Billion BiPAC 7404VGPX.  I found this router and it has some really neat redundancy features.  Failover to land line when ADSL is down and ADSL fail over to a USB 3G device.

However, when I set it up I have not been getting a good voice connection.  When I investigated it more I found that the QOS setting are setup for Australian ISP's.

So if you have any experience setting these up in NZ and getting a good quality voice connection on it, I would love to hear about it.
