Innomedia is decent as well, but again it all depends on loop lengths.
Might want to look at more of a carrier system. Something like a Calix E7, E5 or C7 line. You could probably pick up a C7 chassis on the used market and fill it up with ADSL or VDSL cards that will push dial-tone at least 2x as far as they will push DSL. At least in the 10 mile rage. Although at some point, when you're out past DSL range things like old-school load coils will help with call quality.

Huawei was already suggested and Nokia ISAM also works very well for
your application

Majority of the small consumer gateways (including the 48p ones) will
not work on long loops, they are ment to be used inside a building etc.
