Hi 3cx community I have updated the Firmware for our snom 760 phones by visiting the 3cx management console and going to the "Phones" tab and selecting Firmware->Update. Changes are with the LED's: On an ingoing call the top-right LED is on, when the caller hangs up the LED is off (and doesn't show that a call was missed). The BLF are permanent on, lighting green. Changing when an extension is busy. Is it possible that this is due to the installed firmware: Snom snom760 220.127.116.11 (Up To Date) 18.104.22.168 Snom 760 FW: Maintenance release The maintenance release is confusing me. Is this a pre-relase version which should not be distributed by 3cx yet? I'm thinking in this direction because at the snom documentation (http://wiki.snom.com/Snom760/Firmware/V8) it says the latest version is 22.214.171.124. Has anyone else experienced this issue? Or is this expected behaviour and can I change the behaviour back? On the phones or 3cx? Thanks for any input.
