[Freeswitch-users] VoIP IP DSLAMs

zyxel have what you ask. Huawei have better pricing (~20$ per port)
but huawei wants to sell huge amounts and quality is somehow bad.

Zyxel is quite good (did not try ZyXEL Voip features, only ADSL) but
ADSL is good and reliable, but more expensive per port. There are
options for 12/24/48 and modular 300+ ports
