Snom D735 phones keep randomly trying to update firmware despite being on the latest version

[Stulander]

Title, D735 phones are on firmware 10.1.84.15 but occasionally keep trying to download a firmware update file. Where can I disable this behaviour? Is this on the phone or through 3CX? 3CX automatic updates are disabled.

Thanks

Check whether your network has DHCP Option 66, you might have to disable it.

D'oh!!
I set that the other day and completely forgot about it. Thanks. Problem solved!

Oh. That hasn't fixed it. Some phones keep randomly trying to do a firmware update, even after a reboot. I'll see if there's anything obvious in the phone config.

Are any of the phones setup in SRAPS? At times we will use SRAPS to push firmware updates and remove once ready to deploy.

Nope never used SRAPS.
