<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>The conferencing capabilities of
CallManager along with their hardware DSP resources haven’t expanded
much. Supposedly, you can set parameters higher than 6 but Cisco TAC doesn’t
support it. I believe the issue with the hardware DSP resources of the 6608 or
an HDV-DSP farm module in a IOS router is that audio mixing can’t cross
DSP modules inside the platforms. That’s what limits the max conference
users. When the conference parameter is upped on the software conference bridge
on CallManager it can mix more than six but the higher you set the value the
more processing impact it has on that CallManager. Hence the lack of TAC
support for it, from what I understand. Also the software conference bridge
only supports the G711 codecs without a hardware transcoding resource. Also the
software conference bridge on CallManager can’t cross servers to provide
additional mixing so the conference has to live on one server or the other at
the time it starts.<o:p></o:p></span></font></p>

Conferencing Connection. It’s between CallManager native conferencing and
<st1:Street w:st="on"><st1:address w:st="on">Meeting Place</st1:address></st1:Street>.
It very limited, only supports G711 and in my opinion very buggy with poor
support from the TAC. I used to work for a premier integrator of Cisco IP
Telephony solutions who deployed this for a customer. We didn’t deploy it
ever again.<o:p></o:p></span></font></p>
