Yealink firmware version 66.86.0.5 Phone UI issue

[SLSystAdmin]

I have been watching the issues with the latest Yealink firmware update for ring tones and ring all but no mention of not being able to connect to the web interface for the phone via the "Phone UI" button. Before the update, I could click on this button and the selected phones would open in new windows. Now I get a window that is asking for username and password and no matter what combination nothing works to get logged into the phone interface. I checked and we do have the new 3CX template but still does not work.

The "Phone Web Page Password" should be listed on the Phone Provisioning tab of the extension. Click the eye icon to view it. The default username is "admin".

Tried that, did not work

It use to automatically log in. Is that not an option any longer? I just tried one of the other phones and it worked. Not all are working with this password.

Could it be that the new template has not rolled out to all of the phones yet? I have reprovisioned several and those are now working with their password

 

[SteveITS]

I was going to suggest reprovisioning to ensure the phone has the password set by 3CX. Have not experimented on it but I would think the template change wouldn't change the existing password. However applying the new template did require a reprovision to deploy it.

What @SteveITS said is correct, with the addition that even if you do not reprovision them manually, they will eventually reprovision themselves at some point throughout the day so they will be in sync with the new template. Your passwords are fine, they did not change.

Now, back to the "Phone UI" button: this indeed does not work but not because of the reason you think. Modern browsers now enforce HSTS and this "breaks" the direct UI login feature of the phones.

Edit: we are looking into it to see if we can offer a workaround

I have some phones that are with the older firmware and they word with the Phone UI. only the ones that have the updated firmware do not work with the Phone UI.

Thank you Steve and Frederick, I have checked and manually entering the passwords is working today for the phones that have the new firmware. I still have a couple of phones that have not been updated and those are working with the Phone UI button. I will get the rest of the phones updated today but just wanted to let you know that using the same browser some phones with older firmware is working with the Phone UI button until I update it. As long as I can manually use the password then I am good to go, just inconvenient.

We are aware, after V18 is released we have a fix planned to correct this.
