<div><SPAN style="font-size:10pt;">It does appear as if the GXP-2000 only supports one channel of G729.  You can have many different lines on hold with G729, but the conference feature requires two channels be active and only one of them can be G729.</SPAN></div>
<div> </div>
<div><SPAN style="font-size:10pt;">This is true even if you force the codecs on the phone to G729.  It will use ulaw instead.  Here is the output of the channels showing the last channel is coming in as ulaw on a phone that has G729 throughout.</SPAN></div>
