<p class=MsoNormal>I’m not a fan of forcing every call to “Use MTP
Required” on Device > Gateway > H323 and Inbound Fast Start (which
also forces MTP)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Anyone disagree with me that best practice says you
don’t use G729 as default codec and have CallManager doing Software MTP
transcoding from G729 to G711 and vice <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If you want transcoding you really should do it in hardware,
eh? <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m trying to figure out if someone knew what they
were doing and wanted to force software transcoding at this customer…or
didn’t really know what they were doing.<o:p></o:p></p>
