We looked at CPU and registered devices and such and when all phones were back, we would reset them again, I think we reset each device pool three times in order to ensure all phones got the appropriate load. With over 1500 phones in each device pool, the TFTP server is bound to timeout on a few requests, so resetting the device pools more than once help out. <br><br>Of course, you want to be doing this during a maintenance window.<br><br>---<br>Lelio Fulgenzi, B.A.<br>Senior Analyst (CCS) * University of Guelph * Guelph, Ontario N1G 2W1<br>(519) 824-4120 x56354 (519) 767-1060 FAX (JNHN)<br>^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^<br>Cooking with unix is easy.

This is what I have done in the past. But my question is, in the past it was suggested to only upgrade ~50 phones at a time. Does this change in newer versions of CM? or is ~50 at a time still the best way to roll out firmware on the phones?</div>
<div><br></div><div>follow up question: is there a way to see what phones are on what firmware versions?</div><div><br></div><div>Thanks</div><div><br></div><div>Scott</div>
