Using Asterisk phoneprov as the server
Have multiple modles of phones
VVX310 are running mostly 4.1.4.7430 I have 3 phones at 5.5.0.20556
the server is located in a remote data center. The phones are in the office. I have a Verizon MPLS link between Datacenter and site.
So the only pathway is over the mpls link. During the issue the phones all look like they had to update to the version they were running.
My fix was to inistall a proxy server in the branch site. Point dhcp option 166 to the proxy and load the firmware on the proxy and tunnel back the rest of the traffic.
But now I need to understand the boot process of the phone and how it decides to choose if it has new software so I can fix teh issue permentaly.
