Uploading new Engineering special that contains new firmwares I believe. I have to reboot the Pub & Subs. When the phones move back from being on the Pub will they see the new updates and download them all at once?

The phone will attempt to download a new firmware any time it
downloads a TFTP configuration file that specifies a load different
than the one running currently.

I don't think a failover to a backup server triggers a tftp config
file download.  If the phone lost communication to all servers then
it would most likely end up with a tftp config file download
(depending on the timing of the server coming back).

When I install an OS/Engineering update and reboot to the inactive

swing back over to the subscriber or do I have to manually update
that for each device?



In other words I am worried that all the phones will try to do a TFTP
firmware update after installing the updated OS. Thanks!
