but an MTP cannot transcode. The older NM-HDV transcoders can definitely
do some MTP functions but they may not support some of the newer supplementary
services (particulary around SIP). If you are using a 2851 you
have the newer DSPs and they can most definitely support all of the
supplementary services MTP functions.</FONT></SPAN></DIV>

<P class=pb1body1><EM><SPAN
style="FONT-SIZE: 11pt; COLOR: black; FONT-FAMILY: 'Arial','sans-serif'">Cisco
Unified Communications Manager supports MTP and transcoding functionality
simultaneously. For example, if a call originates from a Cisco Unified IP Phone
(located in the G723 region) to NetMeeting (located in the G711 region), one
transcoder resource supports MTP and transcoding functionality simultaneously.

<P class=MsoNormal style="MARGIN-BOTTOM: 0.75pt"><SPAN
style="FONT-SIZE: 11pt; COLOR: #17365d; FONT-FAMILY: 'Calibri','sans-serif'">So
according to this, a single MTP resource gets enacted to act as both xcode and
supplementary services MTP. That would require a hardware MTP obviously
(software MTP cannot xcode) which is not a problem in this case. I'll have
to do more tracing and stats to get to the bottom of that.<o:p></o:p></SPAN></P>

<P class=MsoNormal><SPAN
style="FONT-SIZE: 11pt; COLOR: #17365d; FONT-FAMILY: 'Calibri','sans-serif'">What
is interesting in this same doc, it states specifically that the WS-X6608 can do
both MTP and XCode, but does not state this for NM-HDV (pretty old info
apparently, don't see anything on newer hardware). That of course doesn't
mean that it cannot perform both simultaneously, but it also doesn't mean that
it can. In this instance, we are using a 2851 with hardware DSP
resources.<o:p></o:p></SPAN></P>
