<DIV dir=ltr><FONT face=Arial size=2>I also have some sample configs on my
laptop at work which I will make available tomorrow. I managed to get hardware
assisted (enhanced IOS) conferencing on a router going nicely after reading the
docs and getting help from the group. And it is fairly simple to get it
configured in CCM as a media resource.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>I also managed to find out the following
useful info. cisco often refers to DSPs and how many conferences etc one can do
per DSP. I figured out now that as far as PVDM2s go a PVDM2-16 counts as one
DSP, a 2-32 counts as 2 and a 2-48 as three and 2-64 as 4. Plus that generaly
for G711 a single DSP (that is one chip on the PVDM can do 8 x 8 meaning 8
conferences with 8 participants. This usually drops to something like 2 x 8 if
you also allow G729 to conference in.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>Also - avoid a PVDM2-8 as far as
conferencing go because it is limited because it counts as a half DSP. Using a
different chip to the rest. It can handle a very small conference apparently but
I have not tried it. Also keep in mind that a single chip can only handle
conferencing and no other function at the same time -- that is share for other
services like transcoding and MTP. However - a single PVDM can do multiple
things like transcoding, conferencing etc as long as conferencing has at least a
dedicated dsp on the PVDM.</FONT></DIV>
<DIV dir=ltr><FONT face=Arial size=2></FONT> </DIV>
<DIV dir=ltr><FONT face=Arial size=2>A lot of people are also worried about
transcoding - normally when they have remote branches with G729 across a wan for
onnet call to a central site and both the HQ and reote site use G711 in the
site. This is not nromally true. The cisco IP phones supports G729 natively and
if you have your regions (for codec selection) and locations correctly
configured the call manager signalling will tell a remote phone to use the G729
codec when talking onnet to an HQ phone across the IP wan.</FONT></DIV>

<P><FONT size=2>Were the questions regarding DSPFARM configs in the email below
ever<BR>answered?<BR><BR>I have configured my DSPFARM on a 2811 but how do you
actually make<BR>these resources the first choice for the users at that remote

but I<BR>can't find a doc specifically for the 2800 routers. Anyone have a
link?<BR><BR>-----Original Message-----<BR>From:
