Auto Provisioning failing

[qss1]

Hi All,

we are having a problems getting a yealink T27G and T27P to auto provision and reboot the phone.
Have configured the phones in 3cx and assigned them an extension all ok, using SBC with a border control ip address.
Browsing to the phones ip address and yealink page > settings tab and auto provision. We add the provisioning server url, hit confirm - then hit the auto provision now button - we get the 'configuration updating' - the phones busy lap flashes but the phone doesn't reboot and take on the config.

We have also tried to re-provision the phone from within 3cx interface by going to the phone list, highlighting the phone in question, but the option along the top of the page to re-provision is greyed out. (see attached)

The server is up to date as is the firmware.

By manually making changes on the yealink page and adding the sip host, username/pwds we can get the phone to register and work. We have 35 phones to setup and don't really want to have to do all this manually though when the autoprovision should work.

Any ideas anyone ??

thanks
AndyM

This is where you are going wrong.
When using a session border controller, it does all the work for you. All you have to do is make sure that in the 3CX server administration, the extension's "Phone Provisioning" tab is properly set up to point to the SBC's ip address. The rest of the configuration is done automatically.

What happens if delete the config within 3CX - remove the phone setup from the extension.

Factory default the phone, and allow the phone to appear within the 3CX console using pnp and then assign the phone to the extension

Also make sure you have port 5001 open on the firewall, as this is port used to provision the phones.

Using SBC you will also need port 5090 open

Then it should work

You should use the assign button to associate the phone with the extension as the phone is not yet provisioned. Once the phone provisions the Reprovision button will become available.

I'm unable to provision T22P phones behind an SBC. They show up in the phones section, but when I assign them to an extension, nothing happens. If I manually configure them with the provisioning link, nothing happens either. Also tried DHCP 66.

I had to disable the PCI compliant SSL settings (Settings -> Security). That fixed the T22P for me.

Glad to see the issue has been resolved and thank you for updating the thread with your solution.
