That is correct.

However, if you install Josh's bridging branch (asterisk/team/file/bridging), 
and use the ConfBridge application, you can get wideband conferencing.

However, you still need a softphone that supports a wideband codec.  If you are 
actually preferring a command line softphone, then my preference is actually to 
just use Asterisk.  It can act as a pretty powerful and highly configurable 
softphone.  :)

If you use Asterisk as the softphone, then use chan_console.  It is set up to 
operate in 16 kHz natively.  Also, use G.722 as the codec between the servers.
