Landline for my home service - 2 lines

[shmvy]

I have just moved into a house with a land line phone connected to the xfinity network. I added a second line for my phone and connect directly to the network ( I don't use the old telephone network as it is wired for 1 number._  I  now need to replace that phone which connects directly into Xfinity. What phone system can I buy that will connect only to the network?

Any touch-tone wired or cordless phone that works with a conventional analog POTS ("Plain Old Telephone Service") line should work with Comcast's home phone service.
