Actually that depends on what equipment you use.

In my case I have an ATA that has a standard telephony jack and an
ethernet jack, so there is most certainly a 2W/4W equivalent type of
conversion going on.

That said, I've never had echo issues with this setup. Echo issues
usually are reserved for lower quality VOIP providers or hardware.
