I am trying to use a Tiptel Cyberbox 100 for VOIP connections (with Twinkle). I see in Twinkle the USB connection alternative does appear, however, the phone doesn't get any sound.
The problem is, I think, due to the dual mode in the Tiptel box: one has to get the box to swtich to USB whereas it is on "Line" by default. In WIndows, the Skype software is doing that or also the X Ten Mate application.
So the question is: how to swtich the box to USB in Ubuntu?
