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><o:p></o:p></p>

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><o:p></o:p></p>

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><o:p></o:p></p>

I have configured my DSPFARM on a 2811 but how do you actually make<br>

assume some configuration in the conf bridge resources and MRGL but I<br>
can't find a doc specifically for the 2800 routers. Anyone have a link?<br>

Hi Ted<br>
<br>
Sounds like you have done it a couple of times.<br>
<br>
Q1. I notice in the config examples they have an example that has<br>
<br>
voice-card 1<br>
no dspfarm<br>
dsp services dspfarm<br>
<br>
bit confusing - why no dsprarm and right below it dsp services dspfarm<br>
???<br>
<br>
Q2. They also show<br>
associate profile 10 register CFB123456789966<br>
associate profile 6 register MTP123456789988<br>
<br>
where does the values after register come from - are they arbitrary<br>
things one choose and need to be unique per site and per profile I<br>
register etc.???<br>
<br>
<br>
oip</span></font><o:p></o:p></p>
