Firmware Upgrade Not Working From Console VIA SBC

[TBWD]

I have have issues trying to upgrade firmware from the management console on a lot of our systems. After the attempt of upgrade nothing happens, phone does not reboot or upgrade.
All phones are provisioned using default templates, OS Debian 9, 3CX is Current. SBC PI, Current install

I've found that sometimes a reboot of equipment including the router helps.

Thank you for that, however, I don't have access do do that, by the time the person come to work that can, the call center is up and working. Was hoping for a 3CX fix if any.

@TBDW try to install the firmware manually on a single phone, just to ensure the phone can jump to that version (should be OK since they are already above 66.84.0.35)

Then if the rest still do not respond, make sure they can get the notification and can also download the file from the PBX. Running a PCAP on 1 of those phones while sending it the upgrade command should show you what happens (or why it fails hopefully)

I will give that a try. Thanks
