<div>Matthew,</div>

<div>I was running V3PN for some time , had major issues with Voice quality as the latency between sites was unpredictable and I had no SLA with the provider for the same. In case you use G.729 between then you might need to try the ccm parrametter mentioned in the second document as before that I was not able to use G.729 due to poor voice quality.In case you are going with it , try going over the V3PN SRND listing out some of the best practices for this. </div>
