Nearly all cordless phones sold in the US use a subset of the same 10
channels, and high-end phones can use all 10, which means that the chances
of someone else being able to listen in on your cordless phone is very high.
The better ones have a handshake between the handset and the base which
keeps random listeners from getting a dialtone, so there's not much
likelihood of people stealing phone service.
But don't plan on having private conversations. The insecurity of cordless
phones is so well-known that they're explicitly excluded from the privacy
provisions of the ECPA. Think of them as the modern equivalent of shouting
over the back fence.
