[cisco-voip] Resetting All Phones on a System

[Simon, Bill]

We usually just watch Realtime Monitoring Tool like a hawk.  Reset some 
batch, watch as they unregister and see that the numbers come back up to 
pre-reset levels.  If they don't, out we go to find out what happened...

(The only time they don't is when there's a firmware load and we do too 
many at a time.  Clogs up TFTP.  I agree with the others who recommend 
resetting smaller numbers of phones at once.  For us that means about 
500 or fewer.  79x1 phones seem to give up more easily than the older 
79x0 phones, but in all fairness, the firmware loads for the earlier 
generation are much smaller.)
