[Asterisk-Users] g.729 - licenses and opinions

[Roger]

I have a few SIP phones, Cisco 7960s, and was looking into implementing 
some compression, ala G.729.  I'm looking into purchasing a g729 
licenses just to get an idea of performance and voice quality, over 
lans, wireless and single channel isdn. 

Does anyone have positive/negative experience w/ getting 
licenses/support from Digium?  Hows the sound quality compared w/ 
g.711?  Is 729 better on slow connections?  Jitter more/less of a 
problem then w/ g.711?  Was implementation a pain?  I've seen the 
bandwidth comparisons @

Things look good... if g.729 turns out to be all it perports itself to 
be then I feel we'd have a real winner.
