Arduino Dial Up Modem shield

Dial Up modem's days are long gone but Land line still exists either in the form of home pbx or PSTN, An Arduino based Dial Up modem shield can be used for a lot of fun projects.
Modem chips are already available with AT Command support
Currently there is no shield to interface arduino with phone line
This shield can also become a base for Arduino corded telephony with additional sheilds for setting up arduino based Home PABX e.g 4 port intercom shield or Voip shield
