I don't use this device, and I generally don't like to use the router functions of an ATA because they are rarely as good as a dedicated router. However, one advantage of having an ATA-router combination device is that you can easily bypass your LAN for purposes of testing VoIP problems (which are usually LAN-related). Routers can generally be set up to do PPPoE authentication, for example, and can be configured to have a routable public IP address (I don't think the PAP2 can do this except as a simple DHCP client). And while you are testing, your computer can still reach the internet (again, not possible where the PAP2 gets the public IP address). Once the VoIP problems are resolved, you can always turn off the device's router functions and go back to using a dedicated router if you choose.

I'm wondering whether these considerations played a part in VOIPo's trying out this device, or is it just because you can get a good deal on them?
