I would only deploy a device pack on new cluster build. All else per device update. I used to like to hardcode the load field on a per phone basis to prevent them from changing. Been doing less of that.
The cmterm CE (Collaboration Endpoint) loads of 1.8GB are ridiculous, in DRS .tar backups too.

Since Cisco already drops support for all firmware older than the most recent firmware: - For each IP Phone model, once Cisco releases a new firmware version, the older versions are no longer supported. - Cisco expects customers who encounter a problem on an older version of firmware to test the latest firmware on a subset of phones in order to confirm that the problem still exists.

Not too mention it clutters up TFTP. I also think that the firmware should be decoupled from the Device Packs. When adding support for a single model phone, rarely am I also trying to upgrade 100% of the phones in the environment too.

Maybe hardcoding the old image on the phone configuration and doing a reset will cause it to boot from it?

My guess is they don’t actually need RMA’ed, just the easiest way to deal with it .... I’d flash the phones and advertise an isolated tftp server to them with the firmware load and XML bootstrap file. The phones aren’t working now, so flashing them and then still not getting them to load right isn’t going to make it any worse. Use DNS in the DHCP scope in your isolation network with the TFTP server and pcap/debug the DNS queries to see the bootstrap and load files it’s looking for. In the 79xx series back in the day when I would perform this Lazarus trick for some lucky customers; the bootstrap filename was XMLDefault.cnf.xml. Not sure if it’s the same nowadays though. Here is the Cisco doc on the procedure for the older stuff .... worth a shot but not sure if it still works on the newer gear. https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/200582-Update-Cisco-IP-Phone-Firmware-through-T.html<https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/200582-Update-Cisco-IP-Phone-Firmware-through-T.html> -Ryan- On Apr 29, 2018, at 18:53, Jason Aarons (Americas) <jason.aar...@dimensiondata.com<mailto:jason.aar...@dimensiondata.com>> wrote: I have a customer with four 8832 conference room phones.

You cannot set an IP address manually.

Cisco TAC says they must be RMA’d. We upgraded CUCM to 12.0.1SR3 and the other two phones upgraded fine from 12.0.1SR2 to 12.0.1SR3. Does anyone have any ideas on what we could do to fix these phones other than RMAing them?
