style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">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.</SPAN></FONT></P></DIV>

<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">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.</SPAN></FONT></P></DIV>

<DIV>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">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.</SPAN></FONT></P></DIV>

<DIV>
<P class=MsoNormal><FONT face=Arial size=2><SPAN
style="FONT-SIZE: 10pt; FONT-FAMILY: Arial">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.</SPAN></FONT></P></DIV>
