What kind of voice connections are you using?  VoIP?  PSTN?   What is
your hardware?

You can probably solve quality issues without doing a complete
reinstall, and you should be able to get reliable results with most
all kernel versions and asterisk versions.  There are some exceptions,
but versions of asterisk and the linux kernel that come with trixbox
have generally been tested to work before trixbox gets released.

If your connections are VoIP, the first area to look at for quality is
network jitter/congestion/drops.  If your connections are analog PSTN,
can you get reliable connections without asterisk in the picture?
Also, if PSTN, is your voice card sharing interrupts with anything
else?

Does that make it less good?  I've found CentOS to be exceptionally
stable, which is my most important criteria.  It has too many services
running by default, but that's an easy problem to solve.
