Thanks for the feedback, I was just checking in. Could have been that it was in the last stages of completion.Please note that since the Snom D810 IP Phone is not currently a 3CX-supported device, we do not have a supported firmware available to provide you with.
Current supported Snom D8 series devices are Snom D812, D815, D862, D865, and SP800 models: https://www.3cx.com/sip-phones/snom-d8-series/
