It depends on where you live, but chances are good that you can still find telecom providers who offer you traditional landline phone service over copper POTS lines. But be prepared for the high costs for both installation and monthly service. Also keep in mind that the aging infrastructure of analog lines make them difficult to maintain, so service may become less reliable over time.
Alternative services provided by THOR Technologies may be a more cost-effective solution and offer more functions than you can get with a traditional landline phone service.
