[cisco-voip] Phone Restart on Subscriber add

[Ryan Huff]

I'll have to lab this up and see what I am missing; last week I added a 9.1.x cluster node and I didnt get any phone bounces during the install.

Strange.

Thanks,

Ryan

>It happens when the cluster becomes aware of the new nodes certificates.  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.
