No beeping sound when call is parked

I am sorry if this is the wrong place to post this, but i’ve tried to contact Yealink Support to no avail.

I have two Yealink T43U phones connected to FreePBX 16.0.40

The user has a BLF for parking extensions on their phone and when they park a call, the BLF lights up as it should, but they do not get the audio alert (beep beep sound) while the call is parked. The audio alert works when the user puts someone on hold though. I don’t know if this could affect it, but there are a lot of users that have the same BLF configuration for the park extensions.(Meaning they see the same BLF light up at the same time.)

I have already factory reset one of the phones, but no luck.

Any help is appreciated.
