Phone upgrade Letter

Thanks for the info but that totally disrupts my setup.  I do not need or want the house phone in the room where the internet connection and cable modem is.  That is a home office that uses a different IP based phone.  So there is no option to just leave things as they are and continue using the phone lines in the wall??  The other problem with this is safety.  Right now one of the best things still about even having a land line is the fact its always powered.  In a power outage a person can plug in an old style push button or rotary phone and they will be powered and work.  This would take that away.
