BLF/Sidecar expansion module on T43U

[PBX_Programmer]

Hi everyone. I've recently installed a V20 3CX system and have added a Yealink sidecar/BLF expansion module onto a Yealink T43U. I have never had to deal with one of these expansion devices before so I am not familiar with them at all. It is connected to the phone with the provided USB cable without an additional power supply and it does light up but I'm not sure if there is maybe something I need to change locally on the T43U to tell it that a sidecar is attached?

I've been trawling forum posts with little success, but I did see something about sidecars being programmed via 3CX handset templates. I don't think I have the ability to customise templates for this particular system so have not attempted that yet.

I have added extra BLF's into the user's setup within 3CX to take it up to a total of 20 and have named/numbered them 1 to 20 just to see if/how they populated the buttons on the phone/sidecar, but they only seemed to populate on the handset as shown in my picture and not on the sidecar. How do I go about programming the buttons on the actual sidecar/BLF expansion module please? I can't find it in any manuals either, and I'm sure I've missed something. I do not currently have physical access to the devices, they are at a remote customer site, so I was hoping to be able to program them via the 3CX admin console.

Thanks!

Add BLF keys 21+ and they will populate to the expansion module. The first 20 keys are on the phone.

Ah I see, thanks for that CentrexJ. I've applied the programming remotely and have asked the end user to confirm if the buttons have been populated. I reprovisioned the phone after making the changes. I wasn't sure whether that step was necessary but I did it just in case.

Yes you for sure have to re-provision or reboot the phone for it to get the updated BLF entries.

I programmed buttons 21 onwards as suggested, and the buttons on the expansion module were indeed populated, however the end user has told me that the first number is missing. It isn't clear whether they mean the first button is blank or the buttons start with the 2nd number. I can see in the config that button 21 is definitely programmed. I'm waiting for them to let me know either way.

The end user confirmed that the first button had shown up on the 3rd page of buttons on the handset. I have therefore moved them all down a row which should in theory move the first button onto the expansion unit. I shall update again when I hear any more from them.
