Hi, We'd like to buy a Snom D712 or D715 as a test, but first I need to make sure BLF works. Looking at the provisioning help page https://www.3cx.com/sip-phones/snom-710-720-760/ I see BLF LED will show monitored extensions in idle. Does it mean that, while in conversation, the BLF leds will not work ? This would make the BLF useless, as people look at it prior to transfer a call for example. Can you confirm ? Thank you !
