I'm running into problems upgrading a brand new ATA-186 (supplied with SCCP v3.1.0 code ) to v3.2.3 code. I'm sure I've managed this before, as our existing ones are all running 3.2.3 code.
We are running UCM 7.1.3 and the Device default is set for 3.2.3 code, with the correct code available on the TFTP servers.
I've tried setting the tftp server addresses directly in the ATA web config, not setting them, adding the CM0&1 servers, and DHCP option 150 is set to give the two tftp server addresses out.
Every time I reset it with any of the changes above, either thorugh software, or with a power cycle. It just boots up and registers with UCM
Any ideas anyone?
