Solved Can't reprovision Yealink T46S

[Pascal Lenier]

Hello!

We have a cloud hosted 3CX and a local SBC.
We use Yealink T23G, T46S and T56A.

Phones appear in MC and get their first provision OK.
After some changes in BLF, we want to reprovision phone to get them.
Clicking "Reprovision" in "Phones" tab works great for the T23G ans 56A but not on T46S !

We tried hard reset, update firmware ( 66.84.0.35 ) and "auto-provisionng" in the phone's web interface, with no luck...
Only hard reset and initial provisionning update the BLF.
Phone call works OK..

Any ideas?

The mac address of the phone correct in 3CX ?

Selected the correct phone type - not using Yealink T46

Is the provisioning url in the phone gui correct ?

Do you use LE certificates provided by 3CX?
Do you have access to 3CX phonebook ?

Thank you for your replies,

• The mac adress is correct.
• The provisionning URL is correct.
• We use the out of the box SSL cert by 3CX, so yes it's Let's Encrypt !

- I tried whith the http provisionning URL, not https and open http in nginx for everyone ( allow all; for http 80 )
=> not working

• The phonebook is working, and can be update "live"
• "Reprovision" and "firmawre" update doesn't works, but "Reboot" Works

Hi Pascal,

Are there any DHCP options running at the phones site?

 

[Pascal Lenier]

YES !
There were a TFTF option left on our lab server when we tested DHCP provisionning years ago!
Now it's working!

It's strange that only the T46S behave like this, and show the correct URL in the Phone Web UI...

Anyway, Thanks a LOT!
The week starts great!
