<DIV><FONT face=Arial size=2>G.729 parameter change is very interesting. I am
using GT.711 just because for the conference feature. Does G.729
support for conference call at remote sites?</FONT></DIV>

<DIV> Manoj,</DIV>
<DIV> </DIV>
<DIV>Your Qos configuration looks ok,I had similar Issues V3PN setup ,some of
the things you need to consider for this kind of setup is</DIV>
<DIV> </DIV>
<DIV>1.Use hardware encryption for VPN as software encryption adds unneccassry
delays</DIV>
<DIV>2.Check the Voice codec for your inter site calls and during a
bad call press the ? key on the phone to check MAX jitter and
RXLOST values.</DIV>
<DIV>3. Do sh policy-map interface to check for drops ,if so see drops change
your priority queue bandwitdhs</DIV>
<DIV>3.There is a service parrametter in callmanager to remove G.729ab,G.729b
from cabablities when calls are established,I had considerable improvement in
voice quality after changing this parrametter to true as by default its
false.I could not use g.729 for voice calls as voice sounded very choppy ,once
i applied this change i am able to use g.729 for calls.</DIV>
<DIV> </DIV>
<DIV>Hope this helps</DIV>

all,<BR>We have hosted PBX system which is located in data centre and we
have<BR>dedicated 1MB internet connection. At present we only have four
remote sites <BR>and all of them have high speed ADSL connection for both
their data and<BR>Voice. Each sites has 4 to 5 phones. We used to use PIX
515 at Data centre<BR>and PIX 501 at remote sites. As we were experiencing
voice quality issue we <BR>moved to Cisco 2821 at Data centre and 800 series
at remote sites. I have<BR>configured DMVPN using GRE over IPSec for our VPN
network. all the tunnels<BR>are up and seems to be working fine so far but I
am just wondering whether I <BR>got right QoS configuration at HeadEnd
Router. As, I am a newbie for QoS, I<BR>have referred various cisco
documentations to configure bellow DMVPN and QoS<BR>for our head end router.
Since we don't have data transaction at HeadEnd <BR>site I think I can use
75% of bandwidth for voice it self. Can some one<BR>help me
figure out QoS requirment for my network environment.<BR><BR>Thank you in
advanced,<BR><BR>Best
