I haven't heard of this particular problem. However, I felt I should comment about how often I keep hearing (a lot!) that putting a call on hold and then taking it off hold solves virtually any audio problems with Express Talk :confused:. I can't determine what the technical explanation is, but it must somehow adjust some audio settings that for whatever reason are not adjusted at other times during the call. I really think the NCH programmers should take a deeper look into this and figure out what exactly about the hold button makes it so magical. I've heard of people who can't talk between Express Talk users at all, but if they put the call on hold and then take it off hold they can speak to each-other just fine.
