<div>Matthew,</div>
<div> </div>
<div>I had a TAC case opened as I could not use g.729 for voice calls for intersite calls over a site to site IPSEC tunnel,it would sound very choppy,after changing this parametter ,I saw a considerable improvement and now I am able to use
g.729 for inter site calls.This is the service parrameeter and this will affect all calls and need to same on both the publisher and subscriber,If you r not seeing any Issues with g.729 over VPN ,I would not recommend changing it to true.

<div> </div>
<div>Manoj, You can use g.729 for conferencing if you use hardware conferrence bridge ,Callmanager software conference bridge will only do g.711 conference and if a g.729 participant wants to jump in then it would make use of a transcorder if one is
available.You can deploy dspfarm at each remote site to be used for conferencing or transcoding.</div>

<p style="MARGIN-BOTTOM: 12pt"><font face="Times New Roman" size="3"><span style="FONT-SIZE: 12pt">Hi 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 regards<br>Manoj<br><br>---------------------------------------------------------------------------
