I don't think I have ever tried it.

Of course you could have one or more broken filters.  Or a broken DSL
modem that is polluting the low frequency range the modem (and voice)
works in, although given you say it happens with just a filter but no
DSL modem, then perhaps the filter is crap.

A crap V.everything seems inconceivable. :)
