Re: Uverse Installer did not remove DSL whole house filter. Are you sure its the same one? If it's mounted in the NID it could be the newer filter for UVerse. If you plug a phone into the modem side you should not have any dialtone. These filters work for ADSL and VDSL.
Honestly if everything looks good and you receive reliable service I would leave it alone, deal with it when it causes a problem.
