> Is there an adapter which allows you to connect an analog phone to a digital phone line? A VoIP analog telephone adapter (ATA) would be the most common form of this these days. Most will have two analog lines, though other configurations are available. The Sipura SPA series and it's derivatives (Linksys PAP2(T), Cisco SPA122) are popular, as well as Obihai's lineup. I've used them all extensively and they're solid. You can connect these to a SIP based VoIP provider or they can operate entirely standalone just calling port to port. With a bit of work you can even link up multiple devices on a private network IP to IP.
