Autoprovision not working after V18U5 update

[phchelpdesk]

Updated to V18 Update 5 last night and now none of our phone systems can provision a yealink phone.

I can register it, but I cant provision it. Anyone else experience this?

We have systems hosted in both google and azure, on windows and linux. The 2 phones I've tried so far are Yealink T46G

For anyone wondering, updating to the latest firmware on the 3CX firmware page fixed this issue.

Thats a known problem and solution for this telephone. This phone is EOL and because of this problem they relased a last firmware to use it that way again.
