Despite the phone resets, the customer’s outsourced security group panicked when they saw a couple thousand packets at the TFTP servers when a sub got added to 10.5 cluster. Guess they thought a DDOS attack was going down or something. Who knows what a 3rd party security company with IDS sensors would think….needless to say it created a small ruckus.

It adds a new TVS entry to the ITL of each node and resets the phones to ensure they download the new ITL before any other ITL changes are made. This is to prevent too many changes happening the ITLs at once making the phones not trust the new ITLs.
