i am using the hosted version
i followed the instructions on the links you sent me........on my phones gui it says working but nothing is happening

Do you have an local sbc server, or are your trying to configure using stun ?

 

[colbyco]

trying direct-sip stun

You have to disable ssl settings within 3cx management console post #2 https://www.3cx.com/community/threads/yealink-t28p-remote-stun-provision-failed.80957/

Also on the phone web interface you have to disable ssl certificate checking under security

Make sure you are running the correct firmware https://www.3cx.com/sip-phones/yealink-t20p-t22p-t26p-t28p/

Note to setup multiply Stun devices from the same location, you need to configure the devices as per 3cx setup

Hi Peter,

If you use hosted, then SBC is indeed the way to go.

1. Once you install your SBC and you see it turn green in your SIP Trunks section, it is now time to reset the phones.

2. Hold the OK button down on the Yealink T23G until you see the prompt to factory reset.

3. Once you proceed and the phone resets, it will boot up back to its main screen.

4. You now have to go into your 3CX "Phones" page and see if the Yealink showed up in bold.

5. If it has, then you tick to select it, and click the "Add Ext" or "Assign Ext" buttons to assign it to a user.
Note: The SBC should be on the the same subnet as the phones for this to work. Also you must not be blocking multicast messages.

6. This takes you to the provisioning tab of said user, where you finally just press OK and then wait about 1-2 mins for the phone to provision itself and reboot automatically.

If you still have trouble with this, you could always contact one of our experienced 3CX Partners who can help you get up and running in no time.

This step is not necessary though - that specific thread was referring to the T28 which is an end of life model.

The T23G should work fine without disabling security.

I finally see my phones on the phone dashboard.........but i can not assign them to an extension i select them but the option to assign them is greyed out.

 

[Saqqara]

Are you logging in the console as the admin user, it will shown you uppercase A in top right if you have ?

Looking at the screen shot you are looking in as admin.

What happens if you create the extension first, then try 'Add to Ext'

Have you already configured the phones within 3CX, if so delete the phone settings under provisioning tab for the extension.

 

[colbyco]

yes as admin user

 

[colbyco]

i deleted the phones from the dashboard and tried to reprovision them again no dice

Hi Peter,

That's good progress so far!

For the T23G, you first need to upgrade the rom to the latest one we offer. You will then be able to assign it.
Please read this guide and go step by step to upgrade, then provision. You should be up in no time

I also noticed a W60 there, that is a DECT phone and the assign buttons do not work for it. Follow these instructions instead and you should be able to get it up and running quickly.

Hello Thread...

I'm having same problem here... My phone was working fine until I tested a full reset of the phone after installing and testing 2 SBC on my lan.

Basically Each SBC have different names and different associated 3CX PBX (2 clients).

I wanted to test the simplicity of the switch from phone direct connection to the 3CX in the cloud to connecting the phones via a local SBC on their lan.

Anyway, at this point one both SBC are up and running and showing green to their respective 3CX servers.

My t23G is on the same lan (with multicast enabled) as the 2 SBC.

On one of the 3CX I can see the "New phone" but not on the second (thats ok for now)

I tried to Assign the phone to an existing extension but nothing is happening, as suggested here I did a full reset of the phone (press ok for 5 seconds..) and still no go... the phone still show as new but will not assign...

I tried disconnecting the second SBC as maybe it was causing interference... but same thing... I ran out of ideas.

Oh on the phone, after reset, it show "Updating config" ... then "Update skipped" (or something like that).

I found a way around it... the T23G by default does not accept any certificates and it seem that the 3CX v18 has one of those not accepted...
So I changed the phone setting to NOT accept Only Trusted Certificates and it works now!

Thanks John,
It worked!
Turned "Only Accept Trusted Certificate" back on and can still update phonebooks!
