Yeah, we still have a landline but I pretty much use it exclusively for outgoing calls. Only my dad and a few other people call the land line. I get a lot of telemarketing calls but i never pick up unless I recognize the caller ID, and nobody ever leaves a message.
I’m on the do not call list, but that law is pretty much unenforceable.
For my business I use a Google voice number that rings through to my cell phone, and I do get occasional telemarketing calls to that line. I can see that they’re dialing the business number, not the cell number.
