Solved BLF buttons no longer green / red on Yealink after v16 upgrade

[delcara]

We have a stack of Yealink phones - T23, T46 etc. - BLF buttons assigned to various extensions - worked perfectly before v15 to v16 upgrade.

Now the buttons on the phones work when pressed, but no longer show red or green. Have updated phone firmware of the phones to match what 3cx wants but no joy. Any ideas?

Thank you!

You likely have them configured with a very old custom template. Move them to the 3CX template and reprovision and it should fix that.

Thanks guys. Used the 3CX template and I've powered the server off and on, still have the same problem.

@delcara What type of license do you have? Can you please refresh your license information from the management console?

It's the first year of the trial, so I'm guessing Pro - however when I go to look I get:

Unable to reach 3CX License Activation Server. Confirm that your Primary DNS Server is able to resolve activation.3cx.com

I've clicked refresh, same error.

Logging into the server, DNS is working, can ping many websites and actication.3cx.com resolves to 151.80.125.88 from that server

Edited resolv.conf and replaced the DHCP'd DNS server (which was an internal server that, to be fair, resolves it properly) with 8.8.8.8 - refreshed license information and it's gone straight in and refreshed the license information.

And that's solved the problem, thank you @JohnS_3CX

Glad it was resolved!
