The goal of the Yeaphone project is to provide a SIP phone for Yealink USB-P1K handsets using liblinphone.
It implements a user interface on a Yealink USB handset <http://www.yealink.com/en/index.asp> for the VoIP software Linphone thus making a PC keyboard and monitor unneccessary. This makes Yeaphone ideal for "Embedded Devices" which work very energy efficient but typically need an extra devices for user interaction (in this case the handset). Parts of the following description emphasizes on the Linksys NSLU2 but the software should work on many Linux-based embedded and PC systems.
