<p class=MsoNormal>I am planning on implementing this on my 7.1.5 cluster
to hopefully speed up firmware updates. I tested this option in our
lab using a test bed of 15 telephones and it resulted in a significant
reduction in bandwidth utilized and time required to upgrade and down grade
7962 telephones. I experienced no issues in my testing.<o:p></o:p></p>
