X3U Pro getting auto created as X3U

[Brendan D]

Version - 18.0 Update 8 (Build 939)
Hosted by 3CX
Using Windows SBC Version: 18.1.36
Fanvil X3U Pro Firmware 2.4.7.4(same issue with 2.4.7.5)

When the phones are added to an existing extension using the Phones section of the management console, they are detected as Fanvil X3U's. When they are added this results in them being provisioned but with no phonebook, BLF support, or 3CX background. Not sure if this is a known issue or not but I was unable to find anything about it and wasted an hour or so troubleshooting till I figured it out.

The fix was to manually create each phone in the extension. However this has resulted in the phones work, but each now now appears under phones twice, once as a new/unassigned phone, and once as a working assigned phone.

Any feedback?

Hi Brendan,

This is because you are not using the correct firmware. https://www.3cx.com/docs/phone-firmwares/

This is clearly visible in the user agent, the ones which have the incorrect firmware are not the same like extension 101.

Using incorrect firmware will prevent 3CX from the detecting the phone model as intended.

Once you take care of the firmware, please delete the phones from the extensions and then add them again from scratch. A factory reset should then be carried out, and the phone will boot up, provision automatically and start working as intended.
