The OBi2182 is a discontinued SIP hardphone manufactured by Obihai (who were acquired by Poly, formerly Polycom). They were “top of the line” in 2017 and 2018, and have a number of cool features, including but not limited to both ethernet and wifi connectivity, support for Google Voice, and the ability to serve as a handset via Bluetooth for a cell phone. Resellers are reselling them for ~60 USD online.
After finally setting up VoIP on my SDF account, getting it setup was a relative breeze. You can do it through the online OBitalk customer portal, but of course, that requires you to set up another account. The OBi2182 also comes with a built in webserver that provides you with the ability to get into the administrative user interface.
This is a quick reference for the settings if you don’t want to use OBitalk. It only includes changes where things are not the default value provided bythe OBi2182. Note: ITSP Profile X just refers to one of the ITSP Profile option groups ([A..F]]), and SPN Service refers to SP[1..6] Service. For an exhaustive desription of the configuration options, consult the Obihai IP Phone Administration Guide (archived link). Consult the fine SDF tutorial for general information about setting up a SIP phone with SDF VoIP.
