There was some confusion over how to use the REMWAVE light phone for video conferencing and screen sharing. One has to use the complete REMWAVE setup or a public video server like nikotels. Since today we offer a complete Linux video and collaboration proxy for download. In order to test the phone you need:

Asterisk or SIP enabled PBX like sipx or SER with other gateways (SIP!!! Not IAX - not yet;-))
REMWAVEs video and collaboration proxy
XMPP server like wildfire, jabberd or a public one like nikotels
