Did anyone ever get an answer to this problem?  I just brought a new 
gateway on line and it is running 12.4 and I have to use g729br8 and 
there are lots of quality issues with noise and errors on * about "extra 
frames".  If I drop the br8 codec, the phones can call out and the 
quality is great, but you can't call in from the gateway.
