encrypted calls with the commercial versions of X-Lite (called eyeBeam) and
Zoiper (ZoiperBiz). While there were problems with eyeBeam I managed to place
encrypted calls (signalling AND media) with ZoiperBiz via FreeSWITCH. Meanwhile
there's an update available for eyeBeam which I have not tested. Maybe it works
now, too.</SPAN></FONT></FONT></FONT></FONT></DIV>
