we got the D375 Phones with Firmware 10.1.42.14
Now i want to display on each phone, the number from that person who are having a phone call or is called.
Phone X phonenumber 10
Phone Y phonenumber 20
Phone Y is in a phone call / is called.
Phone X should show '20' on the Display.
And vise verse.
Is it possible to do that?
For this purpose, I suggest to use the keys on the phone as BLFs if the phones are registered with a phone system or PBX: you can set them from the phone's web interface under the Function Keys menu choosing the "BLF" type and using the other phone extension.
From then on, the phone's LED will show the other phone state (idle, ringing, busy).
For more information about the BLF keys on Snom phones please read the Wiki article (Busy_Lamp_Field)
