Yealink T48G - FW 35.81.0.61 - BLF not working for other Extensions

[arcoMarco]

Hi,

we are currently testing 3CX but we are experiencing a problem having BLF keys working with Yelling T48G phones.
The main problem is that all the BLF keys assigned to the other extensions are showed as "NOT REGISTERED" (grey) even if all the phones are registered.

Please, anyone know how to solve this issue?

Thanks a lot

Had the same issue the other day, i reverted to the firmware 35.73.0.50 and this resolved the issue

Please note that if you are testing V15 with a free license then BLf keys will not work as this functionality is disabled for the free version.
