Zultys Technologies has released a free soft-phone that runs on Linux and provides many of the features of the company's
embedded-Linux-based Zip 4x4 SIP phone, without requiring a separate handset. The Lipz4 (short for "Linux IP Zip 4x4") soft phone is compatible with
"any IP telephony system." Zultys hopes Lipz4 will lower the barriers for companies to explore VoIP technology (Voice over IP), and also serve the
needs of some mobile professionals wishing to minimize device clutter.
