Cisco ATA 186/188

This hard phone is actually an ATA (analog telephone adaptor). It enables you to connect your POTS (plain old telephone system) phones to the Internet. Think of it as a phone jack for VoIP. It has one ethernet port and two RJ11 phone jacks. It is fairly easy to configure. Out of the box, it is configured for DHCP. This means that it gets its IP address from your DHCP server automatically. Full documentation can be found at Cisco's Site.

Since InPhonex works only with SIP protocol, you need to make sure that you are running the correct SIP firmware on your phone. The latest version is 3.0 and can be found here.
