Now after doing some testing with a colleague I found out that the nasty echo effect doesn't stem from the GUS wiring mic to local speakers. It's simple. You hear your own voice delayed by the packet travel time fed back to your opponents mic. When he switched off his speakers the echo was gone. So either you use a head set on both sides or you refrain from using full duplex. Using a telephone you have that environment anyway plus the near light speed signal travel time so that with national connection not even a switching to room speakers would disturb. --Chris Christoph P.
