color:#1F497D'>You may want to upgrade the phones to the 7.X firmware version site-by-site
(or even more granular) before the upgrade while you are still running 4.1.
Then you can have a little more control of when and how many phones are
upgrading at once and the phones won’t ALL upgrade after the switch
version.<o:p></o:p></span></p>

<p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'>We have seen customers in the past also load up local TFTP
servers at each remote site temporarily just to upgrade the phones. Then point
the phones back to the CUCM TFTP after they are all upgraded. This requires
some coordination and in your case with 40 sites, this is less than desirable.
But, something to consider.<o:p></o:p></span></p>
