In a fit of pique at Comcast bricking my Motorola modem I signed up for ATT Uverse including digital voice. Overall I've been pleased with the speed and reliability of the internet and can't say I've noticed much decreased call quality but now none of my fax equipment works and caller ID is hit and miss. Not that fax is a big deal, scan and email is much better, but some institutions require that I accept a fax. I really miss the caller ID. Both are known issues ATT seems to have no interest in fixing. maybe if everyone was last mile digital folks would finally stop faxing, or less likely, the telcos would fix it. Up time has been as reliable as POTS, much better than Comcast whose "qualified technicians" were always in need.
