[Asterisk-Users] G.729? Worth it?

[Luke Catranis]

I do not experience the same issues as below. I personally think g729 is
more then worth the $10 per licensed channel. I have 10 licensed
channels and they are worth every penny. The call quality is far
superior to gsm or g726 and is nearly identical to a g711 call. My
application is probably different then yours, I convert everything to
g711 to my terminators to ensure pristine call quality.

Funny thing about g729, when I setup my server to ONLY allow g729, and
then
put my Cisco 7960's phone into g729 mode, the first call went through
fine
as g729. If I put that party on hold, and dialed another number, that
too
would be g729. But if I tried to call 1 party, and conference in another
party, I got codec warning messages, the phone(s) were trying to make
the
2nd call as ULaw, and what's worst, it try to transform the original
stream
that was g729 into ULaw as well.

I've gotten some strange behaviour of my Sipura and using g729 with
multiple
streams as well. Certain calls try to revert back to ULaw. 

For the most part, I've given up on g729.

There's a MOS scale for this kind of stuff

I think you might want to clarify that Best audio quality is in relation
to 
other highly compressed codecs.  Certainly my (albeit limited)
experience is 
that g711 is much more clear than g729.   Compared against gsm, for
example, 
however, the audio quality is quite good....
