This could be a GREAT tool for researchers say in Australia to discuss
issues with counterparts in the US. You can literally talk for HOURS
and it won't cost you a dime!!!! The only caveat is that it takes
some initial time fiddling with VOX and microphone settings in the
softwares configuration panels.... plan on spending some time tweaking
this...but once you have it ironed out (simple to do - just time
consuming), it works like a CHARM (no pun intended Jerry, ;> ).
Enjoy!
