asterisk users - May 2006 - Speex fans?

Hi all,

I've been testing various codecs to eliminate "choppiness" that I 
sometimes get on my Asterisk IAX2 <> DSL <> provider (Exgn)
connections,
and Speex seems to work the best, so far - but Speex seems oddly unpopular.

Can anyone share their experiences with Speex (good and bad)? Is anyone 
using it in a production environment?

I like the variable bit rate and packet loss concealment features...

I believe the tradeoff is that though it's compressed it uses a bit more
bandwidth and a bit more CPU.  Because of the redundancy to remove chop,
it has greater overhead on almost all counts.  I have no issue using it,
and frequently use it for asterisk <> asterisk trunking where bandwidth
is insufficient for uLaw.
