Not able to provision Yealink T23G

[NoahFromRelyHost]

Hey, I am quite stumped as I am trying to set up my Yealink T23G on 3CX SMB Free. I have inputted the MAC address, factory reset the phone many times and even tried manually putting in the auto-provisioning URL. I checked the logs and can see a 403 Forbidden error from the auto-provisioning. I am not sure what to try next.

The automatic setup just skips to "Update Skipped" at startup and even manually inputting the information results in a registration failed. Any help is appreciated! I have read about an IP blacklist because my firmware wasn't the latest version previously but I am not 100% sure this is the case because this phone never actually successfully registered even on the older firmware.

Have you confirmed that you are using the latest 3CX Supported Firmware version?

Yes I am. I had attempted to connect once previously on an old firmware but it didn't work. I think now I might be IP blocked but I am not sure how to remove the block. I was able to connect directly to Callcentric too so I have determined it's not an issue with the network configuration on my end.

If you have tried previously with wrong firmware your ip most probably is blacklisted.
In this case you will need to wait for 24 hours to be automatically removed.
