discussions with the TAC, before a conference call is assigned to a DSP, it has
to have X number of conference streams available where X is the Maximum Ad Hoc

may have 5 unused channels on the DSP at any time.</FONT></DIV>

style="FONT-SIZE: 10pt; COLOR: navy; FONT-FAMILY: Arial">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>

my opinion very buggy with poor support from the TAC. I used to work for a
