Removing old equipment and cable attached to house

Hello.  We've lived in our house 10 years and have never been an AT&T customer, however the previous owners apparently were as we have an old SBC box and what I assume is a DSL-related box (Arris) attached to the back of our house, as well as a line running from the house to an AT&T junction on a power/telephone pole.  We're replacing our siding and need the boxes and line removed.  Is this something AT&T would actually do?  Is there a specific department I should contact?  Thanks for any info.
