Thanks, this is a really useful setting to know! Previously it has been pretty annoying and non-intuitative to have to press the transfer button twice after announcing a call to a colleague on our Snom 370 phones.
tried that setting but the result is that only the line that rang first will be picked up. My idea was to have a speed dial made of *20* and then pressing one of the BLF lights to pickup that particular light.

Simulated shared line appearance's can be done by using DID's to a custom extension and then register that button on multiple phones. 3CX can do this via SIP forking. I am not sure if the status information shows up properly. but it should work just fine. I don't think you can barge in though without support at the SIP server.
