[cisco-voip] live updates on subscriber - anyone tried it?

[Ed Leatherman]

My question, to which I dont have an answer but i'm sure someone else on the
list does: is there any ramifications to running different OS levels across
your cluster during your upgrade process (assuming several days to update
all the nodes in your systems then at 1 per day)

Also, which server is your TFTP server, or do you have several. not sure how
much of the phones configurations they store incase they cant talk to a
service.

Personally, i'd be just waiting for the rest of the cluster to implode that
same day... murphies law and all that :)
