Hi All, We have just installed 3CX Pro for a customer with Yealink T46 and T48 units with the expansion module. We upgraded the firmware on the phones PRIOR to physical deployment, so the T46's are running firmware 220.127.116.11 and the T48's are running 18.104.22.168, which are both newer than the firmwares 3CX has listed in their 'updates'. When we configure the BLF's on the Expansion Module / Side Car, they show in the list but the lights don't show. If we log into the phone's WebUI and go to the DSS page and click Confirm/Save, it fixes it; although the next time the phone restarts or updates it's config, it goes back to previous. Any suggestions??? I'm wondering if the firmware is not compatible with this version of 3CX.
