Industry-Standard VOIP Phone Using All Free Software

Ralf Ackermann writes: "Voice over IP on a HardPhone running Linux and just using Open Source software became real. We have sucessfully installed and tested (interoperability with Cisco 7960 as well as Pingtel xPressa in an environment with a partysip SIP registrar and proxy) the linphone SIP phone on a StrongARM based TuxScreen. Here is the link describing the steps for others to use the setup as well: TuxScreen running SIP. All the infos for setting up a comparable installation can be found on the URL, please also feel free to ask or drop opinions. Many thanks to the linphone developers as well as to my student Florian Winterstein (for working on a console linphonec version). The setup (on a StrongARM system) is well suited for PDA (iPAQ) or wearable environments as well."
