Maybe your is different but my DSL modem does not have any external filters
on my line although I am sure there are internal filters to keep the voice
frequencies out of the DSL electronics. The filters placed on the telephone
line are low-pass filters to keep the higher-frequency DSL signal noise out
of the voice equipment.

The DSL connection has nothing to do with being able to dial a voice
service. It can't even dial. As was posted earlier you might load a dialler
program via your internet connection, whatever type it is; modem, cable,
DSL, and then the dialler program could access a phone line plugged into the
computer's regular modem if it has one.
