[asterisk-users] g729 and polycoms problem

[Delca]

Still having the same problem. i modified the sip.cfg in order to make
g729 the first choice:

<codecs>
         <preferences voice.codecPref.G711Mu="2"
voice.codecPref.G711A="3" voice.codecPref.G729AB="1"
voice.codecPref.IP_4000.G711Mu="1" voice.codecPref.IP_4000.G711A="2"
voice.codecPref.IP_4000.G729AB=""/>


Cheers,
Santiago
