You can only have about 200-300 subscribers per IPv4 address
The problem with this approach, and with scrubbing centers more generally,
is that while the cure might be better than the disease it doesn't result
in usable VOIP. Voice customers don't care if things are _better_ but
their MOS scores are still below 2.

If they're regularly sending people out to maintain the gear, and saying
it's part of a "ring" that means it's probably part of their
infrastructure and not just a local customer edge device for the building.

This one is always a bit tricky.
For example, if you have an apartment building with say 8 apartments, the
provider can install a larger MDU in a centralized location and potentially

The building owner has no obligation to the provider. If it provides no
value, call them and tell them to remove the equipment if you don't want
it in your building.

It gives them the right to enter the building, but the building can charge “a
reasonable fee” for things like power/space/cooling.
