Solved unable to log in to configure phones after provisioning

[theoa2z3tech]

hi there, my office has a selection of Yealink T40 series IP phones. for the most part they work fine, but whenever i try to log in to them via their IP address to change settings, specifically in this case to display extensions for rapid dialing for my receptionists, i am unable to log in.

Neither the default yealink admin passwords or the new username and passwords generated by 3CX in the phone provisioning tab work, and this was with both carefully writing the username and password out by hand and directly copying and pasting them. i'm genuinely at a loss for why this could be, every thread I've found on this says to simply use the ones 3CX gives you in the provisioning tab. i even tried changing the username and password before re-provisioning and that's only managed to screw up my personal phone. any advice on this would be really appreciated, i am at my wits end here.

just for the sake of being thorough i tested this on multiple phones, both my Yealink T41P, which has some compatibility problems, and one of our Yealink T42S phones, which is a supported phone, and neither works.

Can you confirm that

a) The phones are running the 3CX provided firmware, were initially factory provisioned, and automatically provisioned by 3CX (not manually). Do this first if you are not sure.

b) Have you tried with a Chrome Incognito window to rule out cache / add-ons interfering?

c) You've actually used the "Phone Password" rather than the plain "Password"?
You can click the eye icon next to the extension, in the Phones page of your management console.




What you describe is not the expected behavior, and I have tested T40P, T40G, T41P, T42G, T42S and I was able to log in successfully (using Chrome 106 in my case).

Clearly something else is happening in your case, so I'd suggest you read this first and provide more info so we can better understand how things are set up in case my above recommendations were not able to help out.

sorry about that, i can fill the information out now.

3CX version 18 update 5 built 418
should be Debian 10 as it's a 3CX Azure machine
phones i've tried this on are Yealink T41P and Yealink T42S
provisioned via SBC
IXICA SIP Trunk
Firewall check has passed
I'm not using a custom phone template

as to your questions, i just now factory reset and then automatically provisioned a T42S via our SBC, and attempted to log in via the phones IP address in an incognito window. when i look on my user panel under the provisioning tab i see the window labeled Authentication, which has a username and password. i was under the assumption this is what i needed to log in. how would i get to where you took that screenshot?

at any rate no password i tried logged me into my phones, admin/admin or anything else.

how would i get to where you took that screenshot

Management console > Phones > open the phone > Provisioning > Options > "Phone Web Page Password"

The login is "admin"

okay that was clear as mud, there's like 3 other places with otherwise obvious usernames and passwords, and no mention of a username there, but i am finally able to log in, so thank you.
