You can consider porting your landline number to a VOIP service (I use voip.ms) and after that it's nearly free. I bought a basic Linksys modem (SPA2102) so that we can still plug in our cordless phones in an use them normally.

As a bonus you can set up simple filtering so that you don't get many spam calls. For me, all calls that have an anonymous or 800 number in the caller ID get redirected to a voice prompt that asks the caller to press 9 to talk to us; all other calls just ring our phone directly. You could also use whitelists, blacklists, etc.

It's both better and cheaper than a regular landline...
