I had mentioned to him that configuring the phone to always use a<br>
TRP and then configuring the TRP to support the approriate codecs<br>
might do the trick, but havent tried it yet. the other option was<br>
setting the region between the 6608 and the phone to 723 to force<br>
transcoder invocation, but that seemed messy.<br>
<br>
any comments on either solution?<br>
<br>
